Abstract

At elevated temperatures, N-chlorodifluoromethanimine (CFz= NCl) adds to perhaloalkenes of the type CFz= CFX, forming CFz= NCFzCFXCl (X= F, C1, Br) in good yields. Reaction of these butenes with trifluoromethyl hydroperoxide (CF300H) gives CF300CFzNHCFzCFXC1, and subsequent treatment with KHF, forms the corresponding oxaziridine, OCFzNCF2CFXCl, in excellent yield. Eight new compounds, along with the previously ...
