Abstract
4,7-Decadienal, 4,7-tridecadienal, 5,8-tetradecadienal and 6,9-dodecadienal (all-cis) have been synthesized by coupling 1-bromo-2-pentyne and 1-bromo-2-octyne with the diethyl acetals of 4-pentynal, 5-hexynal and 6-heptynal, followed by partial hydrogenation and hydrolysis. The formation of 1,1,4-triethoxy-2,5-hexadiyne from 1,1-diethoxy-2-propyne is also described.
