Synthesis of Nitro- and Amino-Substituted Thiobenzamides by Thiolation Reactions with Elemental Sulfur at Mild ConditionsThe Synthesis of thiobenzamides 2-7 by basecatalyzed thiolation of nitro-benzyl-halides (type 1), especially at low temperatures, and the selective synthesis of p- and m-nitro-thio-benzamides (2, 3) or p-and m-amino-thiobenzamides (5, 6), respectively, are described. o-Nitro-benzylhalides (→ 4, 7) are less reactive than p- and m-nitro-benzylhalides.The reaction of nitrobenzylhalides (type 1) with elemental sulfur and amines occuring at low temperatures to give 2-4 leads via structures of the type 11, 15 and 16.
