Trapping of the radical intermediate in the photochemical rearrangement of an allyl cloride
Abstract
Direct u.v. irradiation of the αβ-unsaturated trichloromethyl compound (1) gives the β-chlorodichloromethylene compound (2)via the intermediate allyl radical (5), which can be trapped as the β-bromodichloromethylene compound (4) if the reaction is carried out in BrCCl3.
