## Abstract Reaction of [(η^5^‐C~5~H~5~)(CO)~2~M=P=C(SiMe~3~)~2~] [where M = Mo (2), W (5)] with the phosphaalkene __t__BuP=C(NMe~2~)~2~ (1a) afforded the η^3^‐1,2‐diphosphaallyl complexes [(η^5^‐C~5~H~5~)(CO)~2~M{η^3^‐__t__BuPPC(SiMe~3~)~2~}], [where M = Mo (3a); M = W (6)]. Similarly, 2 and CyP=C
Isomerically pure nitrile complexes cis-[Ru(dppm) 2 Cl(NCR)] + (2 a±d) are formed upon chloride displacement from cis-[Ru(dppm) 2 Cl 2 ] (1) or, alternatively, by ligand substitution from the acetonitrile complex 2 a. This latter approach does also allow for the introduction of pyridine (3 a,b), hep
