Journal ArticleDOI
Conversion of Alkyl‐ and Arylallenes into 1‐Alkynes Through Metallated Intermediates.
TL;DR: A number of acetylenes RCH2C=CH have been obtained by metallation of the allenes as mentioned in this paper or mixtures of allenes and allenes with n-BuLi in THF-hexane and hydrolysis after allowing the metallated allenes to rearrange at room temperature or by heating under reflux.
Journal ArticleDOI
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
TL;DR: In this paper, the interaction between di-1-alkynylphosphine oxides and disodium disulfide, sodium selenide and primary amines in solvents like water, methanol, dimethylformamide, liquid ammonia gives the new six-membered heterocyclic systems 2-6.
