REACTIVITY OF T-BUTYL CHROMATE RESINS WITH SUBSTITUTED ALPHA-PHENYLETHANOLS - A KINETIC-STUDY

Polystyrene and polyacenaphthylene supports were functionalized to gen erate a t-butyl chromate function and the resulting polymer-supported reagents were used for the oxidation of alcohols. They were found to o xidize primary and secondary alcohols to the corresponding carbonyl co mpounds in quantitative yields. Oxidation of differently substituted a lpha-phenylethanols was attempted for this purpose and the kinetics of oxidation reactions was studied. The reaction was found to be first o rder with respect to the substrate, the reaction being carried out wit h an excess of the t-butyl chromate reagent. The rate of oxidation was also found to be dependent on the nature of the substrate, concentrat ion of the reagent function, and the nature and concentration of the a cid catalyst used.
