One-pot reactions of sulfinic acid salts (produced from organometallic reagents with SO2) with N-chlorobenzotriazole gave the corresponding N-alkane-, N-arene-, and N-heteroenesulfonylbenzotriazoles 3a-j in 41-93% yields. Reagents 3a-j are efficient sulfortylating agents, reacting at 20-80 degreesC with various primary and secondary aliphatic amines to yield the corresponding sulfonamides in 64-100% yields.
