REACTIVITY OF (triphos)Ni(η2-CS2) TOWARDS GROUP VIB ELEMENTS, HBF4, AND MeOSO2F. CRYSTAL STRUCTURE OF THE DITHIOCARBONATE COMPLEX Ni(S2CO)*0.5THF

The chemistry if (triphos)Ni(η2-CS2) (2) (triphos=1,1,1-tris(diphenylphosphinomethyl)ethane is compared and contrasted with that of the isostructural complex (triphos)Co(η2-CS2) (1).Reaction of 2 with O2, S8,and Sen gives Ni(S2CO(*0.5THF (6), CH3C(CH2PPh2S)3, CH3C(CH2PPh2Se)3, respectively.Methylation of 2 by MeOSO2F, followed by addition of NaBPh4 gives BPh4.Compounds 1 and 2 react with HBF4/diethyl ether to yield the dimers (BF4) and (BF4)2, respectively.The CS2 ligand in 2 is displaced by CO to give the carbonyl (triphos)Ni(CO).The structure of 6 has been determined from counter diffraction data.Crystal data are: a 25.937(15), b 15.560(8), c 23.186(13) Angstroem, β 92.93(5), monoclinic, space group C2/c, Z=8.The structure was solved by the heavy-atom method and refined by full-matrix least squares calculations to R=0.087 for 1464 observed reflections.The nickel atom shows a distorted square planar geometry, being surrounded by two phosphorus atoms of the triphos ligand and by the sulfur atoms of the dithiocarbonate group.

Nucleophilic attack on η2-coordinated dithio acids by hydride ion. A preliminary step in the formation of a variety of nickel complexes

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.
