A diverse array of 2-diazo-1,5-dicarbonyl compounds were formed by the Lewis acid-catalyzed reaction of enoxysilanes with β-hydroxy-α-diazo carbonyls. This reaction proceeds via the Zn(OTf)2-catalyzed dehydroxylation of the β-hydroxy-α-diazo carbonyl to form a vinyl diazonium ion intermediate that is intercepted by the enoxysilane nucleophile to give diazo-containing scaffolds with increased molecular
