Redox hydration or oxygenation under reductive conditions

Redox hydration or oxygenation under reductive conditions 

The presence of added reducing agents has a profound influence on metalloporphyrin catalyzed epoxidatlon of olefins (cf. Section 3.1.4.). In these reactions, alcohols and ketones may also be formed. 

Catalyst systems acting on styrene derivatives under reductive conditions can produce mainly benzylic alcohols (apparent hydration products) and their reduced derivatives. Thus in the presence of BH  

According to this mechanism, addition of a hydridocobalt intermediate HCoL [238] (from BH reduction of the cobalt catalyst) 

An olefin hydration reaction has been reported by Mukaiyama et al, [239], which requires the presence of dloxygen and Coiacac) as
