1H-NMR data (11.74 Tesla) for the gold(I) complexes [R3P-Au-(2,3,4, 6-tetra-O-acetyl-1-thio-β-D-glucopyranosido-S)] (R = Et, Cyclohexyl, C6H5, p-CH3OC6H4) with sulfur coordination to gold, are reported. The resonances associated with the sugar protons have been assigned although these have similar chemical environments. The coordination chemical shifts, Δδ, for the AuSCH proton are ≈ 0.6 ppm, and support
金(I)配合物的1 H-NMR数据(11.74 Tesla)[R 3 P-Au-(2,3,4,6-四-O-乙酰基-1-硫基-β-D-吡喃葡萄糖基-S)报道了具有硫与金配位的](R = Et,环己基,C 6 H 5,对-CH 3 OC 6 H 4)。尽管具有相似的化学环境,但已分配了与糖质子相关的共振。AuSC H质子的配位化学位移Δδ≈0.6 ppm,并支持S与金的配位。
