THE SYNTHESIS AND STRUCTURE OF THE FIRST REPRESENTATIVES OF OLIGOARYLENEPHOSPHOCYCLANES

Abstract
Based on phenylphosphonous acid tetraethyldiamide and 2,2-di(p-oxyphenyl)propane diarylenecyclo-phenylphosphonite is synthesized. Its oxidation and sulfurization is investigated. It is shown that these reactions are stereospecific and lead to cis-isomers. The compounds obtained are the first representatives of oligoarylenephosphocyclanes. The structure of these compounds is confirmed by an X-ray structure analysis.
