    Summary: The textbook represents the shortened, that is the simplifiedversion of IUPAC rules for nomenclature of organic chemistry. Inthis work the number of variations and criteria in naming organiccompounds is reduced and names accepted in newer croatianchemical praxis are chosen. Beside the names of basichydrocarbons and heterocycles, the substitutive andradicofunctional nomenclature of the important compound classeswith characteristic groups are described. Further, stereochemicalnomenclature is presented, where some concepts from recentlypublished works on stereochemistry are used beside IUPAC rules.
    Keywords: nomenclature (substitutive, radicofunctional, stereochemical), characteristic group, IUPAC, radicals

    Summary: This book is intended for practical classes of organic chemistry at faculties and in secondary schools. In the first chapter special attention is paid to security and measures of precautio in an organochemical laboratory. The detailed description of the main laboratory operations (distillation, recrystallization, etc.) and their application in the procedures of purification, isolation and identification of organic compounds folow. In the chapter "Syntheses" and "Isolation and Transformation of Natural Compounds" descriptions of the procedures start with a theoretical part in which definitions, reaction mechanisms, scope and application of particular reactions, etc. are given. At the end of these descriptions there are questions. In the appendix one can find tables with descriptions of characteristies of some dangerous chemicals, their solubility, vapour pressure, and composition of the previously described natural substrates.

    Summary: Synthesis of acids Fn(CHRSXCOOH)2 (Fn=1,1'-ferrocenylene) 1 (X= CH2), 2 (X= CH2CH2) and 3 (X= CH2CH(CH3)) has been presented on the poster by S. Lisac and V. Rapić: Preparation and Reactions of (1,1'-ferrocenylene)bis(thiaaliphatic acids) in section B of this Congress. Reactions of acids 1-3 with trifluoroacetic anhydride gave 15-26% of 2-oxa(3)ferrocenophane 4, 7-13% of dimeric (2,2)ferrocenophane 5 and 10-15% of oligomer 6. Mechanism of these conversions in which S-acylation of the starting thiaacids occured and the stable ferrocyl carbonium ions were formed is proposed. The 1H NMR and mass spectra of the new compounds obtained will be discussed.

    Summary: Condensation of the corresponding ferrocenylcarbinols and 1,1'-ferrocenylenebiscarbinols with mercaptoaliphatic acids HSXCOOH in the presence of trifluoracetic acid gave the title compounds ferrocenylthiaaliphatic acids 1 and 1,1'-ferrocenylenebis(thiaaliphatic acids) 2. Reactions of S-ferrocylmercaptoaliphatic acids 1 with trifluoroacetic anhydride gave instead of expected cyclization products, derivatives of 1,2-diferrocenylethane 3 (23-30%) and similar oligomeric products 4 (15-30%). Under the equal conditions 1,1'-ferrocenylenebis(thialiphatic acids) 2 were converted to 15-16% of 2-oxa(3)ferrocenophanes 5, 7-13% of (2,2)ferrocenophanes 6 and 10-15% of oligomers 7. Mechanism of reactions 1 to 3, 4 and 2 to 5-7 will be discussed. (Aromatic rac,meso-acids 2 were converted into trans-5 in a stereospecific SN1 process.)

    Summary: The widespread use in chiral sulfoxides as intermediates in stereospecific synthesis and the need to know their absolute configuration has given an interest to the chiroptical properties of the C2S and C2SO chromophores.In this work, we have combined the biphenyl chromophore with C2S, C2SO and C2SO2 groups in compounds 1-3. These compounds have been resolved into enantiomers by chromatography on triacetylcellulose, and their CD spectra have been recorded. Since the sulfone group lacks transitions in the accessible wavelength region, the CD spectrum of 3 is very similar to those of simple bridged biphenyls, whereas the CD spectra of 1 and 2 show more complexity, in particular in the region 200-300 nm.

    Summary: The optimal conditions for preparation of aroylferrocene 1 and1,1'-diaroylferrocene 2 were investigated. These compounds wereobtained in 48-99% yields. Reduction of the ketones prepared bysodium borohydride gave corresponding carbinols 4 (20-93%) andbiscarbinols 9 (46-78%) respectively. In reaction of methylisocyanate with carbinols 4 and 9 the nonsymetric ureas 5(22-61%) and bisureas 10 (20-59%) were formed, instead ofcarbamates expected. Condensation of ketones 1 and 2 withcyclopentadiene in basic medium gave desired monofulvenes 6 andbisfulvenes 11 in 53-72 yields; dimers 7 and 12, as well asoligomers 13 (from 2) were obtained as byproducts. They undergoupon heating retro-Diels-Alder reaction giving correspondingmonomers. Structures of the fulvene prepared were confirmed bytheir cycloadditions with acrylonitrile: 6 gave endo-adducts,whereas starting from 11 products of endo- and exo-configurationwere obtained.

    Summary: Friedel-Crafts acylation of ferrocene gave 1,1'-diacetylferrocene (1a) and several 1,1'-diaroylferrocenes (1b-e; acyl=C6H5CO, p-ClC6H4CO, p-CH3C6H4CO, p-CH3OC6H4CO).Ketones prepared were reduced by means of sodium borohydride in 2-propanol to the corresponding 1,1'-ferrocenylenebiscarbinols (2a-e). Reactions of compds. 2 with diethyl malonate gave condensation products 3, which were hydrolized and decarboxylated to beta,beta-(1,1'-ferrocenylene)bis(butyric acid) (6a) and beta,beta-(1,1'-ferrocenylene)bis(beta-arylpropionic acids) (6b-e). Mechanism of these condensation reactions which includes transesterification of diethyl malonate with carbinols 2 has been proposed. Condensation of carbinols 2 with thioglycolic acid, beta-marcaptopropionic acid, and beta-acetylthioisobutyric acid, resp., in the presence of trifluoroacetic acid (TFAA) gave (1,1'-ferrocenylene)bis(thiaaliphatic acids) 12, 14 and 16. Reactions of the thiaacids obtained with trifluoroacetic anhydride (TFA) in methylene chloride gave 15-29% of 1,3-disupstituted 2-oxa(3)ferrocenophanes (18), 9-11% of dimeric (19) and 10-15% of oligomeric products (20). Mechanisms of reactions 12, 14, 16-19, 20 and of the stereospecific conversion of aromatic rac, meso-acids (12, 14, 16) to trans-18 have been discussed. By condensation of aromatic carbinols 2b-d with cysteine and methyl cysteinate, the derivatives of (1,1'-ferrocenylene)bis(S-mathylcysteine) 22 and 23 were prepared. Under similar conditions 1,1'-bis(N,N-dimethylaminomethyl)ferrocene methiodide (24) in reaction with methyl cysteinate gave 2-thia(3)ferrocenophane (26). Mechanism of the unexpected reaction 24-26 has been proposed.

    Summary: By condensation of ferrocylcarbinols 2 with diethyl malonate,followed by hydrolysis and decaboxylation of intermediate esters3, 3-ferrocenylbutyric acid (6a) and 3-aryl-3-ferrocenylpropionicacids (6b-e), were obtained. Reactions of carbinols 2 withthioglycolic acid gave substituted S-ferrocylthioglycolic acids13, which were transformed by means of trifluoroacetic anhydrideinto unexpected products, (derivatives of 1,2-diferrocenylethane15, and corresponding trimeric (16) and oligomeric compounds17).By condensation of aromatic carbinols 2b-d with cysteine andmethyl-cysteinate, the derivatives of S-ferrocylcysteine 20b-dand 21b-d, were prepared. Under similar conditionsN,N,N-trimethylferrocylammonium iodide (22) and1-ferrocenylethanol (2a) gave in reaction with methylcysteinatebisferrocyl sulfide (23) and its homologue 24, resp.
