The general methods, photoinitiated or peroxide-initiated free radical chain additions of halomethanes to olefins, yield 1, 2-addition products at temperatures ranging from 20 to 100° C. At lower temperatures,-42 to-104° C, a competitive reaction, subsequent to the addition of CCl2X, yields alkylcyclopropanes. The reactions of 1-octene or 1-hexene and 1- methylcyclohexene with atomic hydrogen carried out in the presence of several transfer ...
