Reaction of phosphaacetylenes Bu^tC≡P and 1-AdC≡P with (PhSe)₂–XeF₂: first examples of vicinal bis-selenenylation (at P and C) to form novel phosphaalkenes

Abstract

tert-Butyl- and 1-adamantyl-phosphaacetylenes (2 equiv.) react with (PhSe)₂–XeF₂ (→2 PhSeF) to give novel phosphaalkenes by vicinal bis-phenylselenenylation (at P and C), in contrast to acetylenes which undergo fluoroselenenylation.
