The α-regioselective conjugate addition of allyl groups to activated alkenes is a poorly explored area of research. Herein, we report an α-adduct and (E)-isomer selective conjugate addition of allylsilanes to activated alkenes by visible-light photoredox catalysis. The reaction involves allylic radicals that can be generated from allylsilanes through a photoinduced single-electron transfer mechanism. (Figure presented.).

Conjugate allylation of malononitriles is reported using catalytic N-heterocyclic carbene-ligated palladium complexes. This conjugate allylation reaction yields a variety of monoallylated products. These results contrast the bis-allylation of malononitril

Direct addition of alkylzirconocenes to activated alkenes was found, for the first time. Octyl- and decylzirconocene chloride reacted with benzylidenemalononitrile to give the corresponding addition products after hydrolysis in 86% and 79% yield, respecti
Regioselective allylation and alkylation of electron-deficient alkenes with organogallium and organoindium reagents

Triorganogallium and -indium reagents reacted with α,β-unsaturated nitrile and carbonyl compounds to give 1,4-addition products regioselectively. The reaction of allylgallium and allylindium sesquihalides with α,β-unsaturated carbonyl compounds proceeded
