Synthesis of Tricyclohexylphosphonium Bromides from an Air-Stable Phosphine Derivative Reaction of tricyclohexylphosphine-carbon disulfide complex 5 with primary alkyl bromides 4 produces tricyclohexylphosphonium bromides 1 in good yields, making isolation of the phosphine 3 unnecessary. In two cases for 4g, h, rearranged products were obtained.
从一种空气稳定膦衍生物合成三环己基膦鎓溴化物 三环己基膦-二硫化碳复合物5与伯烷基溴4反应生成高产率的三环己基膦鎓溴化物1,无需分离膦3。对于4g,h,获得了重排产物。
