A. Duchene et al., SYNTHESIS OF 3-SUBSTITUTED BUT-3-ENOIC ACIDS VIA PALLADIUM-CATALYZED CROSS-COUPLING REACTION OF 3-IODOBUT-3-ENOIC ACID WITH ORGANOMETALLIC REAGENTS, Synlett, (7), 1994, pp. 524-526
3-Substituted but-3-enoic acids can be obtained in good yields under m
ild experimental conditions by palladium-catalysed cross-coupling of 3
-iodobut-3-enoic acid with organozinc or organotin compounds using PdC
l2(MeCN)2 as catalyst and DMF as solvent.
