Liu, Zhuo published the artcilePh3P+CF2CO–2 as an F– and :CF2 source for trifluoromethylthiolation of alkyl halides, COA of Formula: C8H6BrF3S, the publication is Chinese Chemical Letters (2019), 30(3), 714-716, database is CAplus.
Trifluoromethylthiolation of alkyl halides RX (R = naphthalen-1-ylethyl, 5-chlorobenzothiophen-3-yl, phenylpropyl, etc.; X = Br, Cl) by using Ph3P+CF2CO–2 as a fluoride and difluorocarbene source has been described. Difluorocarbene is a versatile intermediate, but its side reactions are usually ignored and byproducts would therefore be discarded. In this work, side reaction of difluorocarbene and generation of a fluoride anion from the difluorocarbene were developed into a synthetic tool. Although the trifluoromethylthiolation reaction involved multi-sequential steps, the cleavage of C-F bond and the formation of CF2=S bond, F-C(S)F2 bond, and C-SCF3 bond were proceeded fast and completed within 10 min.
