SiliCycle™ SiliaBond™ Functionalized Silica Gels, Pyridinium Chlorochromate (PCC), 40 to 63 μm, 60 Å
Powerful oxidizing agent that minimizes side reactions, greatly facilitates removal of Cr byproducts and is compatible with acid-sensitive protecting groups.
Supplier: SiliCycle™ R24030B10G
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.
Using PCC immobilized onto silica gel provides anhydrous conditions that may otherwise promote side reactions and reduce yields. It greatly facilitates the removal of polymeric-reduced chromium byproducts and is compatible with acid-sensitive protecting groups. When used in conjunction with ultrasounds, kinetics are increased and the amount of oxidant required to complete the reaction is decreased.
Oxidation of 4-tert-butylcyclohexanol to 4-tert-butylcyclohexanone with 2 eq. in anhydrous DCM at room temperature is complete after 6 hours.
