Abstract:
Pd(OAc)2 combined with phosphines catalyzes homolytic cleavage of the C—Cl bond of CCl4 and CCl3CO2CH3 leading to facile addition to olefins under mild conditions. BrCCl3 also reacts with olefins to give 1,1,1-trichloro-3-bromoalkanes. The reaction is accelerated under CO atmosphere, and the presence of bases such as NaOAc or K2CO3 is essential to attain high yields of the adducts.
