An efficient cobalt-catalyzed reductive coupling reaction of alkyl halides
with alkenes bearing electron-withdrawing groups in the presence of water
and zinc powder in acetonitrile gave the corresponding Michael-type addition
products in high yields. The mechanism is discussed.

The simple and inexpensive combination of
TiCl4(2,4,6-collidine) and manganese powder afforded a
low-valent titanium reagent, which facilitated homolytic cleavage of benzylic
C-OH bonds. Radical conjugate addition reactions of various benzyl alcohol
derivatives with electron-deficient alkenes furnished the corresponding
adducts in good yields.

When used with photocatalysis, bench-stable, commercially available
collidinium salts are excellent radical precursors with a broad scope, that can
substitute alkyl halides. Furthermore, all of the reaction components are
water-soluble, which facilitates product isolation.

The ionic liquid [bmIm]OH is a catalyst and a reaction medium for Michael
additions. Although the addition to α,β-unsaturated ketones gives the
monoaddition products, this ionic liquid always drives the reaction of
open-chain 1,3-dicarbonyl compounds with α,β-unsaturated esters and nitriles
toward bis-addition.
