Synthesis of unsaturated acids by 1, 2-addition of formic acid to conjugated dienes catalyzed by palladium on carbon in the presence of mono and bidentate …
Abstract Di-, and trisubstituted 1, 3-dienes are converted to γ, δ-unsaturated acids by use of formic acid, carbon monoxide, and catalytic quantities of Pd C/PPh 3/Ph 2 P (CH 2) 4 PPh 2 in 1, 2-dimethoxyethane. A β, γ-unsaturated acid was obtained when the ...
