The nickel(II) complexes [(triphos)Ni(S2CPEt3)](BPh4)2, [(triphos)Ni(S2CSMe)]BPh4, [(triphos)Ni-(S2COEt)]BPh4, and [(triphos)Ni(S2CNEt2)]BPh4 (triphos = 1,1,1-tris((diphenyphosphino)methyl)ethane) react with NaBH4 to give the complexes [(triphos)Ni{S2C(H)PEt3}BPh4, [(triphos)Ni(π-CS2)], {(triphos)Ni(CO)], and [(triphos)Ni(SH)], respectively. The formation of all of these compounds is suggested to proceed via nucleophilic attack by the hydride ion from NaBH4 on the electrophilic CS2 carbon atom, followed by rearrangement of the resultant adduct. In some cases the reaction is accompanied by a lowering of the metal oxidation state by one or two units.
