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. |
