Formal C(sp 2 )-H and C(sp 3 )-H and C(sp 3 )-Hcross-coupling reactions were carried out by iridium-catalyzed transferdehydrogenation of primary alcohols and sequential manganese-catalyzedinsertion of the formed aldehydes into a carbon-hydrogenbond of aromatic or olefinic compounds.

Rhenium-Catalyzed Insertion of Nonpolar and Polar Unsaturated Molecules into an Olefinic C−H Bond
Treatment of olefins bearing a directinggroup with α,β-unsaturated carbonyl compounds, alkynes, or aldehydes in the presence of a catalytic amount of a rhenium complex, [ReBr(CO)3(thf)]2 gave γ,δ-unsaturated carbonyl compounds, dienes, and allylsilyl ethers, respectively. This reaction proceeds via C−H bond activation, insertion of unsaturated molecules into the formed rhenium−carbon bond, and then
