The complex cis-[RuCl2(dppm)2] reacts with the amine-terminated dithiocarbamates KS2CN(CH2CH 2NEt2)2 and KS2CN(CH 2CH2CH2NMe2)2 to form the compounds [Ru{S2CN(CH2CH2NEt2) 2}(dppm)2]+ and [Ru{S2CN(CH 2CH2CH2NMe2)2}(dppm) 2]+, respectively. The methoxy-terminated dithiocarbamate compound [Ru{S2CN(CH2CH2OMe) 2}(dppm)2]+ was also prepared from the same precursor using KS2CN(CH2CH2OMe)2. The alkenyl complexes [RuRCl(CO)(BTD)(PPh3)2] (R = CHCHBut, CHCHC6H4Me-4, CHCHCPh2OH), [Ru(C(CCBut)CHBut)Cl(CO)(PPh3)2] and [Os(CHCHC6H4Me-4)Cl(CO)(BTD)(PPh3) 2] also react cleanly with KS2CN(CH2CH 2CH2NMe2)2 and KS 2CN(CH2CH2NEt2)2 to yield [MR{S2CN(CH2CH2CH2NMe 2)2}(CO)(PPh3)2] and [MR{S 2CN(CH2CH2NEt2)2}(CO) (PPh3)2], respectively. In a similar fashion, the compounds [RuR{S2CN(CH2CH2OMe2) 2}(CO)(PPh3)2] (R = CHCHBut, CHCHC6H4Me-4, C(CCBut)CHBut) were also prepared. Treatment of [Ru(CHCHBut){S2CN(CH 2CH2CH2NMe2)2}(CO) (PPh3)2] and [Ru{S2CN(CH2CH 2NEt2)2}(dppm)2]+ with trifluoroacetic acid affords the ammonium complexes [Ru(CHCHBu t){S2CN(CH2CH2CH 2NHMe2)2}(CO)(PPh3) 2]2+ and [Ru{S2CN(CH2CH 2NHEt2)2}(dppm)2]2+, while the same reagent generates the tricationic vinylcarbene complex [Ru(CHCHCPh2){S2CN(CH2CH2CH 2NHMe2)2}(CO)(PPh3) 2]3+ through loss of water from [Ru(CHCHCPh 2OH){S2CN(CH2CH2CH 2NMe2)2}(CO)(PPh3)2]. The structures of [Ru{S2CN(CH2CH2OMe) 2}(dppm)2]PF6 and [Ru(CHCHC6H 4Me-4){S2CN(CH2CH2OMe) 2}(CO)(PPh3)2] were determined crystallographically.
