The first lanthanide complex featuring a phosphinidene functional group has been prepared and isolated. Preliminary reactivity studies demonstrate that the lutetium(III) phosphinidene complex, [{2((t)Pr(2)P)-4-Me-C(6)H(3))(2)NLu](2)(mu-PMes)(2), behaves as a phospha-Wittig reagent with aldehydes and ketones to give the corresponding phosphaalkenes. Attempts to use the bulky phosphine H(2)P-2,4,6-(t)Bu(3)-C(6)H(2) to kinetically stabilize a terminal phosphinidene resulted in C-H activation of an ortho-(t)Bu group and formation of a phosphaindole.
