Preparation of α,β-unsaturated esters and amides via external-CO-free palladium-catalyzed carbonylation of alkenyl tosylates
Palladium-catalyzed carbonylation of tosylates with phenyl formate is described. This procedure needs neither external carbon monoxide nor any pressure-resistant apparatus. A variety of cyclic and acyclic alkenyl tosylates can be converted into the corresponding phenyl esters in good yields. Furthermore, this method is effective for the one-pot synthesis of α,β-unsaturated amides.

Palladium catalyzed alkoxy- and aminocarbonylation of vinyl tosylates
Chemical equations presented. The palladium catalyzed alkoxycarbonylation and aminocarbonylation of vinyl tosylates are described. A variety of ketone and aldehyde derived vinyl tosylates may be carbonylated in the presence of primary, secondary, and tert
