The Stereochemistry of Organometallic Compounds. XXXIII. Preparation and Reactions of Some Substituted Buta-1,3-Dienes

Abstract

Hydroformylation and hydrocyanation of 2-methylhex-1-en-3-yne surprisingly both involve addition to the alkyne leading to the formation of formyl- and cyano-buta-1,3-dienes whose reactivity in Diels-Alder and ene-type reactions has been investigated.
