摘要

A wide variety of diynols containing tertiary, secondary, and primary propargylic alcohols undergo a cycloisomerization reaction to form dienones and dienals in the presence of a catalytic amount of [CpRu (CH3CN) 3] PF6. The formation of five-and six-membered rings is possible using this methodology. Secondary diynols react to form single geometrical isomeric dienones and-als. Primary diynols undergo a cycloisomerization as well as a ...
