Corey-Suggs reagent.

Corey, E. J. and W. Suggs (1975) Pyridinium chlorochromate. An efficient reagent for oxidation of primary and secondary alcohols to carbonyl compounds. Tetrahedron Letters 16,2647-2650. 

Pyridinium chlorochromate (PCC) Corey and Suggs prepared PCC by mixing CrOs with pyridine in HCl. PCC is used for the oxidation of primary and secondary alcohols in CH2CI2. This reagent is less efficient than Collins reagent for the oxidation of allyl alcohols. 

Oxidation. This compound has been in the literature for some time, but was recognized as a useful oxidation reagent only recently by Corey and Suggs. It oxidizes primary and secondary alcohols in yields equal to or greater than those obtained with Collins reagent (4, 215-216) and has the advantage that a large excess is not necessary. The oxidations are usually conducted in methylene chloride at room temperature (1-2 hr.). With acid-sensitive substrates, the reaction can be buffered with sodium acetate as in the last example. 

Ni-carbonyl as allylophilic reagent added all at once to a mixture of -decyl allyl carbonate, TMEDA, and dry, argon-satd. dimethylformamide, the stirred mixture warmed slowly to 55°, and the product isolated after 4 hrs. 1-decanol. Y 95%. - Similarly in the presence of water N-Allyloxycarbonyl-dl-phenyl-alanine dl-phenylalanine. Y 83%. F. e. s. E. J. Corey and J.W. Suggs, J. Org. Chem. 38, 3223 (1973).
