An Unexpected Reaction of Trimethylsilyl Fluorosulfonyldifluoroacetate (TFDA) with Imidazoles. Formation of N-Difluoromethylthioureas
摘要:
A new reaction of the efficient difluorocarbene-generating reagent trimethylsilyl fluorosulfonyldifluoroacetate (TFDA) is reported in which molecules containing an N-alkylimidazole or benzimidazole structure undergo an unexpected one-pot conversion to N-difluoromethylthioureas.
