Graphical Abstract
Elimination round: Dehydroiodination occurs when transient phosphinidene complex 1 is treated with iodomethane and diiodomethane, thus formally eliminating CH2 and CHI and giving in both cases complex 2 (see scheme; R=CH(SiMe3)2; R′=CH3, CH2I). The overall reactions represent examples of unprecedented PC bond-cleavage reactions, and proceed under unusually mild conditions.

A total of 47 812 reflections were measured on a Nonius KappaCCD diffractometer using MoKα radiation (λ=0.71073 Å) at a temperature of 123(2) K, 9412 reflections were unique (Rint=0.0697). A semiempirical absorption correction from equivalents was applied (min./max. transmission=0.21995/0.41737). The structure was solved with Patterson methods and refined with full-matrix least squares against F2 of all reflections. Non-hydrogen atoms were refined anisotropically, hydrogen atoms were refined as rigid groups. R values [I>2σ(I)]: R1=0.0263, wR2=0.0432. R values for all data: R1=0.0457, wR2=0.0462, min./max. difference electron density −0.918/0.750 e Å−3. CCDC-606431 contains the supplementary crystallographic data for this paper.
