摘要
beta, beta-Bis(alkylmercapto)propionates were obtained by the reaction of methyl propiolates with 2 equiv. of 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 beta-alkylmercaptoenoates, in which, tri-n-butylphosphine also catalyzed the addition of thiols.
