The dichlorocarbene ligand, in the new complex RuCl2(CCl2)(CO)(PPh3)2, readily undergoes substitution reactions in which the integrity of the metal-carbon bond is maintained.Reactions with species H2X (X=O, S, Se) give chalcocarbonyl complexes RuCl2(CX)(CO)(PPh3)2 while RXH (X=O, S) give new carbene complexes RuCl2(CO)(PPh3)2.Ammonia reacts to give a cyanide-containing complex, RuCl(CN)(CO)(NH3)(PPh3)2, and primary amines, an isocyanide complex, or in the case of certain primary diamines cyclic carbene complexes.RuCl2(CNNMe2)(CO)(PPh3)2 is formed in the reaction with N,N-dimethylhydrazine.Secondary amines, R2NH, react to give chloroaminocarbene complexes, RuCl2(CO)(PPh3)2.
