Infrared, UV/Vis, and W‐band EPR Spectroscopic Characterization and Photochemistry of Triplet Mesitylphosphinidene

Abstract

Monitoring the cleavage of phosphiranes 1 and 2 by using a variety of low-temperature and time-resolved spectroscopic techniques has shown that triplet mesitylphosphinidene (3) is the principal product of this photolytic reaction (see scheme). Results obtained by using laser flash photolysis show that 3 is readily quenched by reactive π systems.
