Abstract

Whereas reaction of [Ru(SOCPh)2(PMe2Ph)2](1) with Ph2PCH2PPh2(dppm) in ethanol (1 : 1 molar ratio) gives mer-[Ru(SOCPh)2(PMe2Ph)3]–dppm, the corresponding reaction with Ph2P(CH2)2PPh2(dppe) gives, after recrystallisation from methanol, the product [Ru(SOCPh)2(PMe2Ph)(dppe)]·MeOH. This has been shown by 1H and 31P-{1H} n.m.r. spectroscopy to consist of two isomers (3a) and (3b) with bidentate and S-bonded –SCOPh groups and the structure of (3b) has been verified by X-ray analysis. The crystals are triclinic, space group P[1 with combining macron], with a= 10.01(1), b= 14.70(1), c= 18.52(1)Å, α= 75.2(3), β= 83.6(3), and γ= 73.5(3)°. Reaction of compound (1) with an excess of PMe2Ph gives an isomeric mixture of mer-[Ru(SOCPh)2(PMe2Ph)3] whereas shaking cis-[RuCl2(PMe2Ph)4] in benzene or methanol for short periods with [NH4][SOCPh] gives the facial isomer. If cis-[RuCl2(PMe2Ph)4] is shaken with [NH4][SOCPh] in methanol for several hours, however, the cation [Ru(SOCPh)(PMe2Ph)4]+ can be isolated by addition of Na[BPh4].
