Pyridinium chlorochromate Usage And Synthesis


Chemical Properties orange crystalline powder


Uses Usually used to oxidize an allylic methylene group.


Uses Oxidizing agent in organic synthesis.


Purification Methods Dry it in a vacuum for 1hour. It is not hygroscopic and can be stored for extended periods at room temperature without change. If the purity is very suspect, it can be readily prepared. [Corey & Scuggs Tetrahedron Lett 2647 1975, Piancatelli et al. Synthesis 245 1982.] (Possible CARCINOGEN.) § Available commercially on a polymer support.
