Oxidations of alcohols based on sulfur reagents

Similarly, reaction of chlorine and DMSO at low temperature gives an adduct that reacts with alcohols, presumably by displacement of chloride from sulfur, to give the ketone and DMSO t 

The development of the CrOs-pyridine complex and the DMSO-based systems has decreased the number of instances in which older oxidation techniques are used. One such method, the Oppenauer oxidation is the reverse of the Meerwein-Ponndorf-Verley reduction (Chapter 3). It involves heating the alcohol to be 

Addition of On gen at Carbon-Carbon Double Bonds 9.2.1. Transition-Metal Oxidants 

A variety of products derived from addition of oxygen at the double bond have been observed using Cr(VI) reagents. Epoxides and ketols are commonly encountered examples, but these reactions are seldom sufficiently clean to be of use for synthesis.  

Chromyl chloride, a volatile liquid with a formal Cr oxidation state of VI, has been found to add oxygen to terminal olefins with formation of aldehydes
