说明

一般說明

Dimethyl sulfoxide (DMSO) is a polar solvent. DMSO activated by electrophile (oxalyl chloride) has been used to oxidize various alcohols (primary, secondary, allylic, benzylic, hindered and bicyclic). Carbonyl compounds are formed as reaction products. It has been proposed as an alternate solvent for methyl cellosolve for use in ninhydrin reaction, due to its high stability.
