Formation of new ring systems by addition of hydrogen sulfide, selenide, telluride, water and primary amines to cyclohexyl‐ or phenyl‐ di(1‐alkynyl)phosphine oxides and alkyl di(1‐alkynyl)phosphinates under nucleophilic conditions

Abstract

AbstractInteraction between di‐1‐alkynylphosphine oxides or di‐1‐alkynylphosphinates and disodium disulfide, sodium selenide, sodium telluride, water and primary amines in solvents like water, methanol, dimethylformamide, liquid ammonia gives the new six‐membered heterocyclic systems 2–6.
