✦ Synopsis

Abstract

The terdentate aryldiamine ligand in the aryltantalum(V) alkylidene complex [TaCl~2~{C~6~H~3~(CH~2~NMe~2~)~2~‐2,6}(CHBu^t^)] (1) controls alkylidene reactivity in a range of metal‐mediated Wittig reactions. An X‐ray diffraction study of (1) shows that the hexacoordinate tantalum centre has a very irregular ligand array in which the aryldiamine ligand adopts a new facial N,C,N coordination mode.
