derivatives are achieved through inter- and intramolecular insertion of alkynes, 1,3-dienes, and alkenes into the C(6)-H bond by nickel/AlMe(3) catalysis. Coordination of the heterocycles to the Lewis acid cocatalyst through their basic carbonyl oxygen is considered to be responsible for the regioselective activation of the C-H bonds, probably through oxidativeaddition to nickel(0).
