Summary: Photochemistry of 4-methylene-2-adamantanone (1) have been
studied under direct and sensitized irradiation. Direct irradition of 1 in
benzene afforded 3:1 mixture of 2-methylenenoradamantane and
4-methylenebyciclo(3.3.1)undec-2-ene-7-al. Irradiation of 1 in benzene in
the presence of benzophenone gave oxetane, the addition product of
benzophenone to double bond, while the major product in the acetone
sensitized photolysis were identified as syn- and
anti-4-(3-oxobutyl)-2-adamantanone.

Summary: The electronic structure of two methylated series of cis-
and trans-norkarene have been studied by photoelectron spectroscopy. The
highest occupied molecular orbirtal (HOMO) in the cis-series is assigned to
the cyclohexene pi-orbital, while in the trans-series HOMO is of a
sigma-type, and is attributed to the twist-bent bond of cyclopropane.

lithiums. The formation of cyclopropane product, 1,2-methanoadamantane (4),
was achieved in good yield only in the reactions of 3 with sodium. The
reactions of 1 and 2 with sodium gave as the major product
1-methyladamantane (5) or 4-methyleneprotoadamantane (6) depending on the
used solvent. However, in the reactions of 2 and 3 with alkyl llithium the
major products were the corresponding adamantane monohalides.

2-amino-2-adamantylcarbonitrile and phenylmagnesiumbromide.
2-Amino-2-adamantyl carbonitriles were prepared in one step using two
methods: at pH 1-6 and via bisulfite addition product.

Summary: A series of selectively deuterated isotopomers of
2-adamantanone, 2-methylene-d2-adamantane and 6-methylene-d2-2-adamantanone
were prepared, and deuterium isotope effects were measured in their C-13
NMR spectra and compared with the effect in the spectra of adamantane
isotopomers. The long range effects delta 3, delta 4, delta 5 and delta 6
were observed and explained by aninteraction of deuterium through the
adamantane cage. These effects confirm the hypothesis that deuterium
behaves like other"real" substituents.

Title: Molecules with twist bent sigma bond. Synthesis and

Summary: Synthesis and reactivity of 1,2-methanoadamantane (1), a
molecule which possesses a twist bent sigma bond incorporated in the
adamantane framework, have been studied. 1,2-Methanoadamantane is
chemically inert to nucleophiles and free radicals, but it is reactive
toward electrophiles and could be easily catalitically hydrogenated. The
reactivity of 1 is consistent with the bond distortion of central
cyclopropyl bond in a trans fused bicyclo(4.1.0)heptane unit. The HOMO of
1,2-methanoadamantane is associated with central cyclopropyl bond but it
seems likely that outside cyclopropyl bonds also suffer a substantional
increase in the strain energy.

Summary: A series of hitherto unknown macrocyclic thioethers
with 1,3-bridged adamantyl system has been synthesized. The synthesis of
4,6:12,14-di(1,3-adamantano)-1,9-dithiacyclohexadecane (3),
4,6:12,14:20,22-tri(1,3-adamantano)-1,9,17-trithiacyclotetracosane (4) and
5,7:15,17-di(1,3-adamantano)1,11-dithiacyclocosane (15) have been achieved
by intermolecular cyclization of corresponding terminal dibromides with
thioacetamide using a high-dilution technique.
Their structural aspects were derived from spectroscopic measurements
and X-ray crystallography. Analysis of X-ray crystal structures 3 and 4
reveals a pronounced preference for gauche placement at C-S bonds. This
preference is expressed by crown thioethers generally and is diametrically
opposite that shown by crown oxaethers.
In the continuation of our studies we have investigated potential
application of various rearrangement reactions in the preparation of
macrocyclic hydrocarbons. It has been shown that the transformation of
macrocyclic thioethers to ring-contracted hydrocarbons can be effected
conveniently by a reaction sequence of m-CPBA oxidation followed by a
Ramberg-Baecklund rearrangement. Ramberg-Baecklund rearrangement of
bissulfone 6 lead to the
3,5:10,12-di(1,3-adamantano)cyclotetradecane-trans,trans-1,7-diene (7)
along with 3,5:10,12-di(1,3-adamantano)cyclotetradecane-cis,trans-1,7-diene
(8) and
3,5:11,13-di(1,3-adamantano)-7,9-dehydro-8-chlorocyclopentadec-1-ene (9) as
a minor products.
The structure of 7 is established by spectral and X-ray
crystallographic determination. In solid stat 7 displays approximately
rectangular shape made up of antiplanar torsions along its sides, with
gauche and anticlinal torsions at each corner.
The conformational behaviour of diene 7 was analysed by dnamic NMR
spectroscopy. Dynamic NMR studies indicated that 7 is conformationally
mobile. At low temperatures ring inversion in 7 becomes slow on the NMR
time scale, whereas at room temperature the molecule rapidly interconverts
from one conformation to another. The ring inversion of diene can most
reasonably be interpreted in terms equilibrium process between
diastereomeric conformers 7a and 7a'. Using the coalescence temperature
method, the transition state free energy was estimated to be ca. 14.2
kcal/mol.

Title: Effect of carbonyl group on the reactivity of
(4.1.1)propellane

Summary: The synthesis and reactivity of
2,3-methano-2,4-didehydro-11-homoadamantanone, derivative
of(4.1.1)propellane (1) are described. (4.1.1)Propellanone is chemically
inert to nucleophiles, oxygen and free radicals, but it is reactive toward
electrophiles and could be easily catalitically hydrogenated. The
reactivity of 1 is explained by decreased electron density at the back side
of the inverted carbon atoms and energy of HOMO of (4.1.1)propellanone, due
to negative inductive effect of the carbonyl group placed in the
alfa-position to the central propellane bond.
Keywords: intramolecular cycloaddition, 2,3-methano-2,4-didehydro-11-homoadamantanone, inductive effect, propellanones, carbenes
