- • Numerous examples of oxidations with this reagent are to be found in Organic Syntheses. For directions for preparation of chromic acid (Jones) reagent, see: Org. Synth. Coll., 5, 866 (1973).
- • For preparation of alumina-supported reagent, and use in chemoselective oxidation, for example of allylic alcohols, see: Synth. Commun., 24, 1823 (1994). For selective oxidation of aliphatic alcohols to aldehydes in ether/water, see: Chem. Ind. (London), 312 (1989). Has also been used catalytically in the presence of a co-oxidant, see Sodium perborate tetrahydrate, A10189, and Periodic acid, B20433.
- • Several CrO3 based reagents have been developed, usually with the objective of increasing selectivity, of which CrO3:(Pyridine)2 (Collins' reagent) is probably the most widely used. For a procedure, see: Org. Synth. Coll., 6, 644 (1988). However, to control the highly exothermic reaction (possible fire hazard!), the reagent is probably best prepared and used in situ in dichloromethane: J. Org. Chem., 35, 4000 (1970); Org. Synth. Coll., 6, 373 (1988);or acetonitrile: J. Org. Chem., 45, 1135, 1142 (1980). The use of Celite. as a support for the reagent has been found to be beneficial: same ref. and: Synth. Commun., 3, 115 (1973); Tetrahedron Lett., 2079 (1973). See also Pyridinium chlorochromate, A11752, 2,2'-Bipyridine, A15782, 3,5-Dimethyl-1H-pyrazole, A10157, and Potassium chlorochromate, A19000.
