Partial hydrogenation of 1,2-dienes occurs readily and, in most cases, gives useful levels of regioselectivity and E/Z stereoselectivity. Early interest in this area was prompted by curiosity as to whether the axial chirality of an allene could be transformed into central chirality in the resulting alkene.
