Novel Gold(I) and Silver(I) Complexes of Phosphorus-11-dithiolates and Molecular Structure of OO’-(Bornyl)2PS2H3NC(CH3)3

摘要

BackgroundThe 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 (¹H-, ¹³C- and ³¹P-) 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.
