Abstract: | A new and intriguing methodology to access various O‐difluoromethylation oxime compounds from ClCF2H, TBN and indoles is developed under mild reaction conditions. This strategy can suppress N‐difluoromethylation of indoles successfully, in which there are two different active species (:CF2 and ·NO) while indoles are unprotected, featuring simple operation and radical involvement. |
