Rhodium- and palladium-catalyzed 1,5-substitution reactions of 2-En-4-yne acetates and carbonates with organoboronic acids
(American Chemical Society, 2011-08)
Two methods involving the rhodium-catalyzed reaction of 2-en-4-yne acetates and the palladium-catalyzed reaction of 2-en-4-yne carbonates with organoboronic acids were investigated; both afforded exclusively the (E)-configured ...
Rhodium catalysed chemo- and stereoselective arylative and alkenylative cyclisation reactions of unsymmetric diynes containing a terminal alkyne moiety with organoboronic acids
(Royal Society of Chemistry, 2010)
Unsymmetric diynes possessing a terminal alkyne moiety reacted with organoboronic acids both chemo- and stereoselectively to afford arylated or alkenylated exocyclic dienes by catalysis from the [Rh(cod)OCH 3] 2 complex. ...
Synthesis of α,β-unsaturated ketones by rhodium-catalyzed carbonylative arylation of internal alkynes with arylboronic acids
(Georg Thieme Verlag, 2008-10)
The Rh-catalyzed reaction of arylboronic acids with internal alkynes under a CO atmosphere in the presence of an acid additive afforded α,β-unsaturated ketones as the major products. Hydroacylation of internal alkynes, ...
