Synthesis of -Methylene Complexes

These complexes of the general type M(/ -CH2)M containing direct M —M bonds may be obtained by reactions of various complexes with the following  

Complexes with / -methylene bridges are also formed in reactions of metal carbene compounds with systems such as M(PR3)2 (M = Ni, Pd, Pt) which are isolobal to the CH2 group [reactions (3.17)-(3.21)].
