Whereas HgR2 (R=methyl or aryl) converts trans-(Ru(CO)2Cl2(PMe2Ph)2) exclusively into (Ru(CO)2R(Cl)(PMe2Ph)2) and does not react with cis-(Ru(CO)2Cl2(PMe2Ph)2), LiR reacts with either isomer to yield (Ru(CO)2R2(PMe2Ph)2) and also catalyses conversion of the trans isomer into the cis.The initial attack by R- is belived to be on a carbonyl ligand.Treatment of (Ru(CO)2R(Cl)(PMe2Ph)2) with LiR' yields mixed complexes (Ru(CO)2R(R')(PMe2Ph)2).In all cases the two organic ligands are mutually cis.The dimethyl complex undergoes reversible carbonylation to form mono- and di-acetyl complexes, and (Ru(CO)2Me(Ph)(PMe2Ph)2) also forms an acetyl coplex, but aryl ligands are unaffected by treatment with CO.
