| Abstract: | As for RuCl2(PPh33], carbonylation of RuCl2(PR3)3] PR3 = P(p-tolyl)3, PEtPh2) in N,N 1-dimethylformamide (dmf) gives Ru(CO)Cl2 (dmf) (PR3)2] (II). For PR3 = PEtPh2, rearrangement of (II) in various solvents gives inseparable mixtures (31P evidence) but for PR3 = P(p-tolyl)3 Ru2(CO)2Cl4-{P(p-tolyl)3}3]is obtained. Reaction of Ru(CO)Cl2 (dmf) - {P(p-tolyl)3}2] with RuCI2{(P(p-tolyl)3}3] (1:1 mol ratio) gives Ru2 (CO) Cl4 {P (p-tolyl)3}4] whereas reaction of Ru (CO) Cl2 (dmf) - (PPh32] with (Rul2 {P (p-tolyl)3}3] gives Ru2(CO)Cl4 (PPh3)2] - {P(p-tolyl)3}2] - Reaction of RuCl2 {P(p-tolyl)3}3] with CS2 gives the related Ru2Cl4(CS) {P(p-tolyl)3}4] and {RuCl2(CS)}P(p-tolyl)3{2}2] whereas RuCl2(PEtPh2)3] and CS2 produce RuCl2(S2CPEtPh2) (PEtPh2)2]CS2 and Ru2Cl4(CS)2(PEtph2)3]. |
