Abstract

Abstract Image

The reaction of Ph3PCH2 with Mo(NAr)(CHCMe3)[OCMe(CF3)2]2 (Ar = 2,6-i-Pr2C6H3) produces the anionic alkylidyne complex {Ph3PMe}{Mo(NAr)(CCMe3)[OCMe(CF3)2]2}. An X-ray structure determination of the complex reveals a bent Mo−N−C angle for the imido group, as expected when a metal−carbon triple bond is present. The anion has been shown to react with electrophiles predominantly at the imido nitrogen.
