Diol reaction with h2so4

WebHere is a mechanism emphasizing the role the Lewis acid might play in catalyzing the reaction: This reaction works in a similar way to the Nencki reaction (2) In order to get the form of the molecule shown as the … WebThe reaction is concerted. That is, all the steps are happening at once in a daisy chain fashion. It is the same with OsO4. The pi electrons of the double bond move to one of the O atoms in OsO4, and the electrons again move in a concerted mechanism to give a cyclic osmate ester. 3 comments ( 3 votes) Upvote Downvote Flag Cortes Lupe 9 years ago At
