Olefins conjugated with carbonyl, carboxylic ester, and phenyl groups as well as highly strained non-conjugated olefin norbornylene were converted to their corresponding α-hydroxy-β-cyanoadducts by treatment with mercuric fulminate and lithium bromide. The transformation appears to go through a 1,3-dipolar cycloaddition of metalfulminate to the olefin followed by a spontaneous cleavage of the resulting
