G. Ferguson et al., NOVEL PHOSPHONIUM-BETAINE LIGANDS [SC(H)PPH(3)-C,S]- AND [S(H)C=C(PPH(3))S-S,S']- STABILIZED IN RHODACARBORANE COMPLEXES, Journal of the Chemical Society, Chemical Communications, (13), 1994, pp. 1595-1596
Two novel phosphonium-betaine ligands [SC(H)PPh(3)](-) and [S(H)C=C(PP
h(3))S](-) are stabilised in the twelve-vertex close-type rhodacarbora
ne complexes 3-{eta(2)-SC(H)PPh(3)}-3-(PPh(3))-3,1,2-RhC2B9H11] and [2
-{eta(2)-S(H)C=C(PPh(3))S}-2,1,7-RhC2B9H11] which are characterised sp
ectroscopically and by X-ray diffraction methods.
