Abstract:
Olefins are hydroxylated by reaction with water and an oxidant, particularly an organo-hydroperoxide, in the presence of an osmium-halogen compound hydroxylation catalyst such as OsCl 3 and optionally in the presence of a co-catalyst such as a transition metal halide.
Abstract:
A process directed to the hydroxylation of olefins by reacting said olefins in the presence of oxygen, water, and a catalyst composition comprising (i) a catalytically active osmium containing compound, (ii) a Co-catalyst I comprising a copper containing compound such as CuBr 2 , and (iii) a Co-catalyst II capable of increasing the rate and/or selectivity of the hydroxylation reaction, such as pyridine is disclosed.

Abstract:
A process for the hydroxylation of olefins comprises reacting the olefin with an oxygen containing gas and water in the presence of a defined catalyst composition. The catalyst composition comprises (i) a catalytically active oxide of a specified metal such as OsO 4 , (ii) a co-catalyst I being a specified transition metal salt such as CuBr 2 , and (iii) optionally a co-catalyst ll being a salt such as tetra ethyl ammonium bromide.
