摘要

Newman-Kwart重排法（NKR）是由o -芳基硫氨基甲酸酯合成s -芳基硫氨基甲酸酯的有效方法。然而，需要苛刻的温度条件，导致底物降解和副反应。此外，使用杂芳香族底物的反应相当罕见。本文报道了Bi(OTf)3在常温条件下使用杂芳香族底物催化NKR。该反应不仅扩展到氮杂芳烃底物，而且扩展到噻吩底物。

Bi(III)-Catalyzed Newman–Kwart Rearrangement for Synthesizing S-Heteroaryl Thiocarbamates

Newman–Kwart rearrangement (NKR) is a useful method for synthesizing S-aryl thiocarbamates from O-aryl thiocarbamates. Harsh temperature conditions are required, however, leading to substrate degradation and side reactions. Moreover, reactions using heteroaromatic substrates are quite rare. Herein, we report Bi(OTf)₃-catalyzed NKR using heteroaromatic substrates under ambient temperature conditions. The reaction extended to not only aza-arene substrates but also thiophene substrates.
