Preparation and Decarboxylation of Allenyl Acetic Acids: a Route to Substituted Buta-1,3-dienes
Baldwin, Jack E.,Bennett, A. R.,Forrest, Andrew
, p. 250 - 251 (1987)
Propargylic esters undergo the Claisen ester rearrangement to give acetic acids which thermally decarboxylate to give substituted buta-1,3-dienes.

We have developed a gold-catalyzed isomerization of unactivated allenes into 1,3-dienes with nitrosobenzene as an additive. This reaction proceeded almost exclusively at room temperature for highly substituted allenes. The utility of this reaction is manifested by the development of one-pot [4+2]-cycloaddition of allenes and reactive alkenes.

(Chemical Equation Presented) An efficient, one-pot method for the conversion of carbonyl electrophiles to allylic chlorides has been developed, by activating magnesium alkoxides in situ using TiCl4.
Decarbopalladation of π-allylpalladium intermediates formed from palladium-catalyzed arylations of 3-allen-1-ols

eqution presented Unusual palladium-catalyzed arylative fragmentations of acyclic 3-allen-1-ols were observed. Oxidative addition of Pd(0) to aryl halides would form the arylpalladium halides, which added to the central carbon of allenes via carbopalladation to form the π-allylpalladium intermediates. The π-allylpalladium intermediates would be reductively eliminated via carbon-carbon cleavage to give the arylated dienes and the α-hydroxyalkylpalladium intermediates, which were further reductively eliminated to the corresponding aldehydes.

The reactions of the [Ru(C5Mej)Cl]4 tetramer with 2, 4-diphenylpenta-l, 3-diene or 3-phenyl- or 1, 5-diphenyIsubstituted pentadienyl anions lead to the incorporation of the expected phenyl-substituted pentadienyl ligands into the respective symmetric Ru(C
SELF-CONDENSATION OF ALLYLIC ALCOHOLS MEDIATED BY TiCl4
Idrissi, Mostafa El,Santelli, Maurice
, p. 1531 - 1534 (2007/10/02)
Addition of Grignard reagents to enones associated with TiCl4 leads to dehydration and Diels-Alder-like reaction giving dimeric hydrocarbons in good yields.
