Reactions of strong bases with beta-triphenylstannyl substituted propi
onitriles give high yields of alkenes under mild conditions through, p
robably, an E1cB mechanism; under the same reaction conditions, beta-t
rialkylstannyl substituted propionitriles give substantially lower yie
lds of elimination products.
