Abstract: Esters of glyoxylic acids are formed by the oxidation of an organoglycolate ester using a hypohalide oxidizing agent, preferably under phase transfer conditions using a phase transfer catalyst. An example of a suitable oxidizing agent is sodium hypohalite, and a preferred starting material is methyl mandelate.

Abstract: Alkyl vanadates are prepared by the reaction of vanadium pentoxide and an alkyl alcohol while heating in the presence of an alkane azeotroping agent to assist in the removal of water by-product. In a representative example triisobutyl vanadate is prepared by the heating of isobutanol and vanadium pentoxide in the presence of n-heptane.
