| Abstract: | CIDNP effects were found in the Ni(acac)2-catalyzed reaction of Et3Al with CHCl3. The effects appear in the products of transformation of the diffusion radical pair of the ethyl and dichloromethyl radicals. The radical route is a side process in this reaction, and the main products, Et2AlCl, ethane, and ethylene, are formed by a nonradical route. A general mechanism of the reactions of Et3Al with CHCl3 and CCl4 including radical and ioncoordination processes was suggested. Translated fromIzvestiya Akademii Nauk.
