addition reactions of very weakly acidic nonactivated alkylarenes such as toluene and its derivatives were developed by using a strongly basic mixed catalyst system under mild reaction conditions. The addition reactions with imines and alkenes proceeded smoothly under proton‐transfer conditions to afford the desired products in good to high yields, and high levels of regio‐ and stereoselectivity were achieved

Catalytic benzylic C–H alkylation reactions of alkylarenes with alkenes such as β-substituted styrenes and vinylsilanes have been achieved by utilizing alkylpotassium as a catalyst. Various substituted toluene derivatives can be alkylated under mild reaction conditions to afford the desired functionalized hydrocarbons in moderate to high yields.
