We have synthesized bismuth complexes incorporating polydentate mono- and dithiolate ligands and examined their utility as water-tolerant Lewis acid catalysts. The reaction of Bi(OAc)3 or Bi(NO3)3·5H2O and the corresponding mono- or dithiol(ate) yielded the compounds [(SNNS)Bi(OAc)] (4), [(SNNSPr)Bi(OAc)] (5), [(NNS2)Bi(OAc)] (6) and [(ONS2)Bi(OAc)] (7), [(ONS2)Bi(NO3)] (8) and [(NNS)2Bi][NO3] (9)
我们已经合成了包含多齿单硫醇和二硫醇配体的铋配合物,并研究了它们作为耐水路易斯酸催化剂的效用。Bi(OAc)3 或 Bi(NO3)3·5H2O 与相应的单硫醇或二硫醇(酸)反应生成化合物 [(SNNS)Bi(OAc)] (4), [(SNNSPr)Bi(OAc) ] (5), [(NNS2)Bi(OAc)] (6) 和 [(ONS2)Bi(OAc)] (7), [(ONS2)Bi(NO3)] (8) 和 [(NNS)2Bi] [NO3] (9) [H2(SNNS) = N,N'-二甲基-N,N'-双(2-巯基乙基)乙二胺;H2(SNNSPr) = N,N'-二乙基-N,N'-双(2-巯基乙基)丙二胺;H2(NNS2) = N,N-二乙基-N',N'-双(2-巯基乙基)乙二胺;H2(ONS2) = 2-甲氧基乙基-双(2-巯基乙基)胺;H(NNS) = N,N-二乙基-N'-(2-巯基乙基)乙二胺]。4-8
