Aerobic oxidative cleavage of C C bond to carbonyl compound

Photoinduced C-C bond cleavage in dithiane-carbonyl adducts: a laser flash photolysis study.

Molecular fragmentations induced by oxidative electron transfer present a fascinating theoretical challenge and generate a great deal of interest due to their potential applications. It is well-known, for example, that in vicinal diols, amino alcohols, and amino ethers, C-C bonds weakened by photoinduced electron transfer cleave efficiently and selectively. Mechanistic aspects of this cleavage ...

H2 Elimination and C-C Bond Cleavage of Propene: A Theoretical Research

Propene dissociation channels were characterized by ab initio CCSD(T)/6-311++g(d,p) calculations. Inthis work the detailed mechanism of propene dissociation to C2H4+CH2, C2H2+H+CH3, C2H2+CH4 andC3H3+H2+H have been investigated. According to our calculations, ten fragments can be classified intofive dissociated channels. Our results point out that two mechanisms come into play in the H2 eliminat...

Copper-catalyzed aerobic radical C–C bond cleavage of N–H ketimines

We report herein studies on copper-catalyzed aerobic radical C-C bond cleavage of N-H ketimines. Treatment of N-H ketimines having an α-sp(3) hybridized carbon under Cu-catalyzed aerobic reaction conditions resulted in a radical fragmentation with C-C bond cleavage to give the corresponding carbonitrile and carbon radical intermediate. This radical process has been applied for the construction ...

Selective Carbonyl-C(sp3 ) Bond Cleavage To Construct Ynamides, Ynoates, and Ynones by Photoredox Catalysis.

Carbon-carbon bond cleavage/functionalization is synthetically valuable, and selective carbonyl-C(sp3 ) bond cleavage/alkynylation presents a new perspective in constructing ynamides, ynoates, and ynones. Reported here is the first alkoxyl-radical-enabled carbonyl-C(sp3 ) bond cleavage/alkynylation reaction by photoredox catalysis. The use of novel cyclic iodine(III) reagents are essential for ...
