A metal-free, efficient, practical, and convenient process based on an iodine-catalyzedoxidativecleavage reaction has been developed to form 1,2-diaryldiketons in high yields from 1,3-diaryldiketones. The reaction is performed in DMSO and in air, and a mechanism was proposed according to the reaction evidence.

Methylamine-water system was developed as a new methyl source for the methylation of β-diketones under mild photocatalytic reaction conditions. Degree-controllable deuterated methylation could be easily achieved by using distinct combinations of d-methylamine-D2O system, allowing for the synthesis of deuterium-labelled bioactive molecules with a controllable number ranging from 0 to 3.

A transition-metal-free oxidative methylenation reaction was developed. Methylene-bridged bis-1,3-dicarbonyl compounds were synthesized by oxidative C(Sp(3))-H activation and C-N cleavage of N-methyl amines. This novel reaction avoids the use of transition metal catalyst. Furthermore, the reaction are very mild and operational convenient. (C) 2014 Elsevier Ltd. All rights reserved.
