Abstract

A stereoselective C-H activation reaction of a NMe group of [Ta{C6H4CH(Me)NMe2-2}-(CH2Ph)2Cl2 (1b) affords toluene and a species which was isolated as the new pentagonal bipyramidal Ta(V) tetrahydrofuran (THF) adduct [Ta{C6H4(CH(Me)N(Me)CH2)-2}(CH2Ph)Cl2- (THF)] (2). The chirality of the arylamine leads to a single structurally characterized diastereoisomer in which intramolecular coordination of the modified amine group produces a triangular Ta-CH2-N unit.
