The synthesis and characterisation of [Pd(S2CNEt2)(Ph2PCH2CH2PPh2]+ salts of some chloro- and bromo-metallate anions—X-ray crystal structures of [Pd(S2CNEt2)(Ph2PCH2CH2PPh2)+[MCl2]− (M = Cu, Ag)

dithiocarbamates) [M(S2CNR2)2] (M = Pb, Zn, Cd, Hg, Cu, Ni, MoO2, VO; R = Et, Bun), in refluxing dicloromethane, to afford the known complexes [|PdCl(S2CNR2)|2] in virtually quantitative yield. In boiling acetonitrile the diphosphine complexes [PdX2(Ph2PCH2CH2PPh2)] (X = Cl, Br) react readily with bi- and trivalent metal diethyl dithiocarbamates [M(S2CNEt2)n] (M = Pb, Zn, Cd, Hg. Ni, MoO2, VO n = 2; M = Co, Fe
钯配合物[PdCl 2(PhCN)2 ]容易与金属双(二烷基二硫代氨基甲酸酯)[M(S 2 CNR 2)2 ]反应(M = Pb,Zn,Cd,Hg,Cu,Ni,MoO 2,VO; R = Et,Bu n),在回流的二氯甲烷中,得到已知的络合物[| PdCl(S 2 CNR 2)|。2 ]几乎定量的产率。在沸腾的乙腈中,二膦配合物[PdX 2(Ph 2 PCH 2 CH 2 PPh 2)](X = Cl,Br)容易与二价和三价金属二乙基二硫代氨基甲酸酯[M(S 2CNEt 2)n ](M = Pb,Zn,Cd,Hg。Ni ,MoO 2,VO n = 2; M = Co,Fe,Mn,n = 3)得到通式[Pd(S 2 CNEt 2)(Ph 2 PCH 2 CH 2 PPh 2)] 2 + [MX 4 ] 2-。铜(II)和银(I)的二乙基二硫代氨基甲酸酯形成[Pd(S 2 CNEt 2)(Ph
