Details

SiliaBond® Pyridinium Chlorochromate (Si-PCC) is used for the general oxidation of alcohols to carbonyl compounds, selective oxidation of allylic and benzylic alcohols, organometallic oxidation, oxidative transpositions, oxidative cleavages, allylic and benzylic oxidation and oxidative cyclizations.1-4

Using PCC immobilized onto silica gel provides anhydrous conditions that may otherwise promote side reactions and reduce yields. It greatly facilitates removal of polymeric reduced chromium by-products and is compatible with acid-sensitive protecting groups.5,6 When used in conjunction with ultrasounds, kinetics are increased and the amount of oxidant required to complete the reaction is decreased.7-9

Oxidation of 4-tert-butylcyclohexanol to 4-tert-butylcyclohexanone with 2 eq. in anhydrous DCM at room temperature is complete after 6 hours.
