Article abstract of DOI:10.1021/jo00289a038

Generation of chlorofluorocarbene by reaction of CFCl3 with reduced titanium at O deg C, in the presence of various alkenes, produces 1-chloro-1-fluorocyclopropanes in good yield.Evidence from the syn/anti product ratios, including generation of chloroflu
