Synthesis and stereochemical aspects of 2,6-disubstituted perhydroazulenes - Core units for a new class of liquid crystalline materials
A novel approach for the synthesis of cis/trans-fused perhydroazulenes 13-19 is reported. The stereochemistry of the derivatives of carbene addition products 9a-c/20-22, of the 2,6-disubstituted perhydroazulenes 12a-c/23-25, and that of compounds 26-27 has been studied by single-crystal X-ray crystallography. The hydrogenation of the tropylidene to the perhydroazulene skeleton under various conditions is described. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

Synthesis of Biological Markers in Fossil Fuels. 2. Synthesis and 13C NMR Studies of Substituted Indans and Tetralins
Unambiguous syntheses of all possible methyl, ethyl, n-propyl, and n-butyl derivatives of indan and tetralin were developed using the Kumada coupling procedure involving the reaction of aryl or vinyl halides with Grignard reagents in the presence of nickel(II) chloride.An analysis of the 13C NMR spectra of these compounds was also completed.
