Novel Gold(I) and Silver(I) Complexes ofPhosphorus-1,1,-dithiolates and Molecular Structure of [O,O '-(Bornyl)(2)PS2]H3NC(CH3)(3)

Background: The novel chiral phosphorus-1,1-dithiolates [4-CH3OC6H4P(S)(OR)S]-[H3NC(CH3)(3)](+) were synthesized by the reaction of [RPS2)](2) (R = 4-MeOC6H4) or P2S5 and the respective alcohol ROH (R = myrtanyl, 2-naphthylethyl, myrtenyl, borneol) in toluene. The reaction of phosphorus-1,1-dithiolates 1-4 and Au(tht)Cl, AuClPPh3 or AgNO3 and PPh3 gave rise to gold(I)- and silver(I)-complexes in THF. All compounds have been characterised by elemental analyses, IR, NMR (H-1-, C-13- and P-31-) spectroscopy as well as MS measurements. Optical rotation values confirmed the chirality of the compounds. The Compound 4 has been characterized structurally by X-ray crystallography.
