The transition metal catalyzed cross-coupling reaction of alkane di-Grignard reagents with carboxylicacid derivatives provides a convenient one-step synthesis of symmetrical 1,n-diketones (n ⩾ 8) and long-chain dicarboxylic thiol esters.

The formation of a C(sp(3))-C(sp(3)) bond by oxidative ring-opening homocoupling of cyclobutanols was explored. A broad scope of 1-substituted cyclobutanols were transformed into C(sp(3))-C(sp(3)) bond-formation products by oxidative ring opening in good to high yields under exceptionally mild conditions in an open flask in just 30 s.
