Furan compounds

A method for obtaining 2-aryl derivatives of 4,7-dihydro- and 4,5,6,7-tetrahydroisoindoles from the products of the diene synthesis of 2,5-dimethoxy-2,5-dihydrofuran with aliphatic and cylic dienes is described.See [1] for Communication XLIII.Deceased.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1443–1445, November, 1970.     

Nitrogen-fluorine compounds

The experimental and theoretical chemistry of nitrogen-fluorine compounds is an area that has seen considerable renaissance over the past decade. This review is not exhaustive in scope but rather focuses on and highlights certain aspects in this field. In particular (but not exclusively), the chemistry of binary N-F species is discussed.     

Alkoxy compounds

Six 2, 2, 5-trialkyl-5-α-alkoxyethyl-1, 3-dioxanes have been synthesized for the first time by the condensation of 2-alkyl-2-α-alkoxyethyl-1, 3-propane diols with ketones, and it has been shown by a study of their PMR spectra that they exist in the unsymmetrical boat conformation. The PMR spectra of a number of previously-synthesized 2-alkyl(aryl)-5-alkyl-5-α-alkoxyethyl-1, 3-dioxanes have been considered and it has been shown that from an analysis of the spectra it is possible to estimate the contents of geometrical isomers in a mixture. The stereochemistry of these compounds has been discussed.     

Organoboron compounds

Summary Treatment of alkaneboronic eaters with alkyllithiums yields dialkylborinic esters.     

Vinylboron compounds

Summary A general method for synthesizing unsaturated boron compounds was developed.
