Abstract

Phosphinidenes have been proposed as short-lived intermediates in several reaction systems.'We have reported products from the photodecomposition of 1-mesitylphosphirane that are in accord with the formation of free mesitylphosphinidene (2) as a reactive intermediate. 2 Product structures suggest that mesitylphosphinidene adds to? r-bonds in a fashion similar to that for carbenes and silylenes.* J But, heeding Mathey's warning ...
