Sodium bismuthate glycol cleavage

Sodium bismuthate (NaBiOa) was first used by Rigby as an oxidant for a-glycol cleavage reactions to give carbonyl compounds (equation 1), and was found to be similar in scope to lead tetraacetate and... [Pg.703]

The mechanism of 1,2-cleavage of glycols with sodium bismuthate is generally considered to be similar to that with lead tetraacetate and periodic acid [40CB563], although there is still some controversy [50JCS(C)1907]. A cyclic bismuthate diester is postulated as a plausible intermediate, though the rates of oxidation observed are not so different between cis- and trans-, 2-cyclohexanediols. [Pg.373]

Glycol cleavage by oxidation with sodium periodate, lead tetraacetate, or sodium bismuthate, is a useful method for determination of the ring size of glycosides as well as for the assignment of anomeric configuration and position of substituents on the ring. (See Chapters VI and I.)... [Pg.215]
