Represented is a CuX2- or I2-promoted ring-opening dual halogenation of cyclopropenones with saturated oxygen heterocycles, providing an efficient method for the synthesis of 3-haloacrylates. The ring-opening reaction enables the construction of two C–X (X = Cl, Br, or I) bonds and a C–O bond as well as the cleavage of two C–O bonds and a C–C bond in a single step. This protocol is highly atom economical, has an excellent substrate scope, and exhibits the ability for gram-scale reaction.

Ketones can be easily obtained by electroreduction in an undivided cell of an organic halide-metal carbonyl mixture using a Ni-bpy catalytic system in DMF (bpy = 2,2'-bipyridine). The process is especially well convenient for primary benzyl and alkyl halides.
Self-Termination and Electronic Spectra of Substituted Benzyl Radicals in Solution
Claridge, Rodney F. C.,Fischer, Hanns
, p. 1960 - 1967 (2007/10/02)
Several substituted benzyl radicals have been generated in liquid cyclohexane by the photolysis of symmetrically substituted dibenzyl ketones.The rate constants for self-termination to substituted bibenzyls, and absorption spectra of the transient radicals, have been measured by optical modulation spectroscopy.The termination rates are generally well described by the von Smoluchowski equation with a spin factor of 1/4.Deviations are discussed in terms of steric retardation and the unreliability of the estimated reaction diameters of radicals with bulky substituent groups.Absorption spectra of the three monomethyl-, the three monochloro-, two dichloro-, and the three monomethoxybenzyl radicals demonstrate the influence of the substituents on the energy levels of the benzyl system.
