A high-yield synthesis of trans-RuCl2(CS)(H2O)(PPh3)2 from RuCl2(PPh3)3 and CS2 is described.The coordinated water molecule is labile, and introduction of CNR (R=p-tolyl or p-chlorophenyl) leads to yellow trans-RuCl2(CS)(CNR)(PPh3)2, which isomerises thermally to colourless cis-RuCl2(CS)(CNR)(PPh3)2.Reaction of AgClO4 with cis-RuCl2(CS)(CNR)(PPh3)2 gives +, from which + and + are derived.Reaction of trans-RuCl2(CS)(H2O)(PPh3)2 with sodium formate gives Ru(η2-O2CH)Cl(CS)(PPh3)2, which undergoes decarboxylation in the presence of PPh3 to give RuHCl(CS)(PPh3)3.Ru(η2-O2CH)H(CS)(PPh3)2 and Ru(η2-O2CMe)H(CS)(PPh3)2 are also described.
