Abstract
Abstract Lithium aluminum hydride is a homogeneous catalyst for the selective hydrogenation of 2-pentyne and conjugated dienes to monoolefins. Deuterium tracer experiments involving 1,3-pentadiene have shown that the metal hydride and gaseous hydrogen each donate one hydrogen atom to the diene. LAH adds to 2-pentyne in a trans manner. The mechanism of the hydrogenation reaction is discussed.
