Di- and trisubstituted 1,3-dienes are converted to γ,δ-unsatd. acids by use of formic acid, carbon monoxide, and catalytic quantities of Pd-C/PPh3/Ph2P(CH2)4PPh2 in 1,2-dimethoxyethane. A β,γ-unsatd. acid was obtained from isoprene (a monosubstituted diene).

Abstract
Di- and trisubstituted 1,3-dienes are converted to γ,δ-unsatd. acids by use of formic acid, carbon monoxide, and catalytic quantities of Pd-C/PPh3/Ph2P(CH2)4PPh2 in 1,2-dimethoxyethane. A β,γ-unsatd. acid was obtained from isoprene (a monosubstituted diene).File in questo prodotto:
