A transfer hydrogenation process for forming vicinal diols by hydrogenating 1,2-dioxygenated organic compounds using alcohols as the reducing agent instead of the traditional H2 gas. The transfer hydrogenation is carried out under milder conditions of temperature and pressure than is typical for ester hydrogenation with H2. The milder conditions of operation provide benefits, such as lower operating and capital costs for industrial scale production as well as savings in product purification due to the avoidance of by-products from exposure of reaction mixtures and products to high temperatures.
Ester compounds of the formula I-a wherein R1 is selected from OH, NH2 and NH3+X-, wherein X is an inorganic anion, wherein R2 is a singly-branched saturated or unsaturated aliphatic hydrocarbon moiety selected from C7 - C15, wherein R5 is selected from H, and a linear saturated or unsaturated aliphatic hydrocarbon moiety selected from C6 - C14, and wherein R2 and R5 together have a total of 7 to 15 carbon atoms; that are useful as antibacterial or antifungal compounds in consumer products.
