A metal-free protocol for the selective cleavage of unstrained C–C single bonds was developed. Under the catalysis of KI and in the presence of NaHCO3, the readily available α-chloro-β-hydroxy ketones underwent bond breaking and sulfonylation smoothly to afford β-ketosulfones with high efficiency and broad substrate scope. Mechanism investigations, both experimental and theoretical, showed that a retro-aldol cleavage/nucleophilic substitution sequence might be involved.

1,4-Diketones were prepared by cerium-catalyzed oxidative coupling of styrene with molecular oxygen and 1,3-dicarbonyl compounds. This two-step sequence was performed as a one-pot procedure without isolation of the intermediate products. The first step is

Heating 2-acyl-alkane-1,4-diones 1 to temperatures above 120 deg C causes an acylgroupmigration leading to 3-acyl-alkane-1,4-diones.
