the dialkylphosphinothioation reaction of alcohols and phenols with tetraalkyldiphosphine disulfides in high yields. Phenols were reacted in the presence of RhH(PPh3)4 and 1,2-bis(dimethylphosphino)ethane under THF reflux, and alcohols with Pd(OAc)2 and 1,2-bis(diphenylphosphino)benzene under chlorobenzene reflux. Primary alcohols reacted faster than secondary alcohols under these conditions, and protected
过渡金属络合物以高收率催化了醇和酚与四烷基二膦二硫化物的二烷基膦硫醇化反应。苯酚在RhH(PPh 3)4和1,2-双(二甲基膦基)乙烷的存在下在THF回流下反应,而醇与Pd(OAc)2和1,2-双(二苯基膦基)苯在氯苯回流下反应。在这些条件下,伯醇的反应比仲醇的反应更快,并且将受保护的酪氨酸和丝氨酸进行了硫代磷酸化,且消旋作用极小。四苯基二膦二氧化物也经历了P–O键的形成反应。
