mercaptanes in the presence of tri-n-butylphosphine in high yield. The corresponding dithioacetals could be also obtained by the conjugate addition of mercaptanes toward methyl β-alkylmercaptoenoates, in which, tri-n-butylphosphine also catalyzed the addition of thiols.
摘要 β, β-双(烷基巯基)丙酸酯是由丙炔酸甲酯与2当量反应制得。在三正丁基膦存在下以高产率合成硫醇。相应的二硫缩醛也可以通过硫醇与β-烷基巯基烯酸甲酯的共轭加成得到,其中三正丁基膦也催化硫醇的加成。
