A sulfoxantphos modified palladium-catalyzed synthesis of α,β-unsaturated carboxylic acids from alkynes with CO and H2O was described. The atom-economic hydroxycarbonylation of various symmetrical and unsymmetrical alkynes can be achieved with chemo-, stereo-, and regioselectivity, affording the corresponding carboxylic acids in good to excellent yields. Using water as the reaction solvent, the water-soluble palladium catalyst was easily separated from the product and could be reused for 5 cycles.

Irradiation of a solution of 2-vinylstilbene (1) under anaerobic conditions gives 9-phenyltricyclo2.7>deca-2,4,6-triene.Derivatives of (1), substituted at the α-position of the stilbene double bond, give 2-substituted 3-phenyltricyclo4
