1. The polarizability ellipsoids of the triphenyl derivatives of group IV elements do not have axial symmetry. 2. The effective conformations of the aryl radicals in these molecules correspond to eclipsing of the adjacent bonds.

It was established that 2,5-dibromo-3-R-4-arylthiophenes form organodimagnesium compounds in ether with the “accompaniment” of dibromoethane. It is shown that because of steric hindrance, only 2-ethoxalyl-3-R-4-arylthiophenes are formed in the re

The 2,2-dimethyl 1,3-diketones with methyl and aryl radical substituents exist largely as conformations in which the carbonyl group and the C-Me bond are shielded.

The reactions of organomagnesium derivatives of 2-methyl- or 2,3-dimethyl-7-azaindoles and 2,3-dimethylbenz[4,5]- or -[6,7]indoles with diethyl oxalate, and the reactivity of the resulting ethoxalylindoles towards phenylmagnesium bromide, have been e
