Fused in the same molecule! An N‐heterocyclic carbene and a diphosphine are generated and used in the modular synthesis of a variety of target heterometallic complexes. The experimental approach involves formation of a unique 4,5‐bis(diphenylphosphino)‐1,3‐dimethyl‐imidazolium salt, simply by starting from 1‐methylimidazole (see scheme; M 1 =Cr, Mn; M 2 =Au, Rh, Pd; LiHMDS=LiN(SiMe 3 ) 2 ).
