A remarkably diverse reactivity toward Lewis acids is exhibited by the phosphanylcarbene (R 2 N) 2 PC̈SiMe 3 (R c ‐C 6 H 11 ). The methylated Lewis acids MMe 3 (M Al, Ga, In) undergo 1,2 addition reactions to form the C‐substituted phosphorylides 1 (X Me), while the corresponding chlorides MCl 3 form the first stable phosphanylcarbene–Lewis acid complexes 2 (X Cl).
