kanes, , react to give good yields of the homoallylic substitution product, . Less reactive organocuprates react with to give mixtures of and the direct substitution product, . These results are consistent with a copper(I) radical intermediate which undergoes facile rearrangement prior to reductive coupling.

Reaction of piperidine with 1-bromo-1-cyclopropylalkanes, , afforded excellent yields of the homoallylicsubstitution product, , when the bromine-bearing carbon was sufficiently sterically hindered.
