found to effect regioselective addition of cyanoformate esters across 1,2-dienes, giving rise to 3-alkoxycarbonyl-3-butenenitriles. Functional groups such as cyano, protected hydroxyl, and amino groups in the 1,2-diene substrates are tolerated. Isomerization of the initial products to thermodynamically more stable isomers takes place possibly through further oxidative addition of the C-CN bond of
