Palladium catalyzed reactions of α-bromo-α,β-unsaturated carbonyl compounds with 1-(E)-alkenylboronic acids
A new synthesis of functionalized 1,3-dienes is described based on the palladium catalyzed coupling reaction of 1-(E)-alkenylboronic acids with α-bromo-α,β-unsaturated carbonyl compounds. Key words: Palladium; Alkenyl; Boronic acid; Catalysis

Carbonylation of Enynes under Hydroformylation Conditions Catalyzed by Rhodium Carbonyl. A New Method for Synthesis of Cyclic Enones
The reactivities of 1-buten-3-yne derivatives toward hydroformylation were studied using a rhodium catalyst.Unexpectedly, cyclopentenone derivatives were obtained in moderate yields together with formyl-substituted dienes and unsaturated lactones.This rea
HYDROFORMYLATION AND HYDROCARBONYLATION OF ENYMES BY RHODIUM CARBONYL CLUSTER: A NEW ROUTE TO CYCLIC ENONES
The reaction of but-1-en-3-yne derivates with carbon monoxide and hydrogen in the presence of Rh4(CO)12 catalyst gave formyl-dienes, cyclopentenones and unsaturated lactones, which shows the CC is much more reactive than the C=C moiety and may provide
