Efficient Synthesis of Thiobenzanilides by Willgerodt-Kindler Reaction with Base Catalysts

摘要

Willgerodt-Kindler reaction between anilines and benz­aldehydes readily proceeded in the presence of catalytic amount of Na2S·9H2O to give thiobenzanilides in moderate to good yields. The base catalyst was also available for preparation of primary thio­benzamide.
