Bougioukou, Despina J,Smonou, Ioulia
, p. 339 - 342 (2007/10/03)
The chloroperoxidase (CPO)-catalyzed oxidations of dienes conjugated to an ester group were studied using tert-butyl hydroperoxide as the terminal oxidant.

Ruthenium-catalysed reductive cleavage reactions of allylic carboxylates and carbonates with formic acid and triethylamine to give olefins were explored.As an application of the ruthenium-catalysed processes, a new synthetic route to α-hydroxy acids has been discovered.The reductive cleavage of allylic esters is considered to proceed through ?-allylruthenium intermediates. Key words: Ruthenium; Catalysis; Reductive cleavage; Allyl; Formic acid
Cobalt(II) catalysed reaction of alkenes with aliphatic aldehydes and molecular oxygen: Scope and mechanism
Bhatia, Sonika,Punniyamurthy,Bhatia, Beena,Iqbal, Javed
, p. 6101 - 6122 (2007/10/02)
A variety of cobalt(II) complexes can be prepared using Schiff's bases derived from aromatic aldehydes and amines or α-aminoesters. These complexes are versatile catalyst for the reaction between aliphatic aldehydes and various alkenes. The outcome of the reaction is controlled by the electronic nature of the alkene as the electron deficient alkenes undergo oxidative addition of aldehydes followed by dioxygen incorporation to yield 2-hydroxy(acyloxy)-4-oxoesters or nitriles whereas unactivated or electron rich alkenes afford the corresponding epoxides. These reactions are proceeding via a radical pathway and a common acylcobalt intermediate is proposed for the formation of 4 as well as the epoxides 7.
