Abstract
The addition reaction of iododifluoroacetates to alkenes is initiated by copper powder (10-20 mol% I at 50-60" C. Both terminal and internal alkenes give good yields of adducta. The reaction is also applicable to alkenes containing a variety of functional groups, such as epoxy, hydroxy, ketone, eater, and phoephonate moieties. This reaction can be carried out either neat or in solvents such as hexane, benzene, acetonitrile, DMF, DMSO, and HMPA ...
