Abstract
A new linear acetylide-connected bis-phosphorane, acetylene-bis[triphenyl)phosphorane] ( 2) was synthesized in the reaction of triphenyl(phenylethynyl)phosphonium bromide with dilithioacetylide. Triphenylbis(phenylethynyl)phosphorane ( 1) was also prepared by a similar treatment of triphenyl(phenylethynyl)-phosphonium bromide with lithium phenylacetylide.
