Aromatic organocopper compounds (phenyl-, m-, p-tolyl-, o-anisyl-copper) react with CS2 to give unstable copper compounds, except for o=tolycopper, from which polymeric o-TCSSCu (o-T=o-tolyl) and another derivative, probably [o-TCSSCU2]n, were obtained. Tritylperoxide is the main by-product in the reaction with phenyl copper. Arylcopper(I) complexes with triphenylphosphine and diphos undergo insertion
芳香族有机铜化合物(苯基- ,米- ,p甲苯基- ,ö -anisyl铜)与CS反应2,得到不稳定的铜化合物,除了Õ = tolycopper,从该聚合ø -TCSSCu(ø -T = ø - tolyl)和另一种衍生物,可能是[ o -TCSSCU 2 ] n。三苯甲基过氧化物是与苯基铜反应的主要副产物。芳基铜(I)与三苯基膦和双膦的配合物经历CS 2的插入反应,形成相应的二硫代羧酸盐配合物ArCSSCu(PPh 3)2和(ArCSSCu)m-(diphos)n(m = 1,n = 1; m = 2,n = 3)。它们通过与CH 3 I反应得到几乎纯净的ArCSSCH 3。已经确定了PhCSSCu(PPh 3)2的晶体结构。
