Heck reaction of aryl halides with linear or cyclic alkenes catalysed by a tetraphosphine/palladium catalyst

cis,cis,cis-1,2,3,4-Tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C 3H5)]2 system catalyses efficiently the Heck reaction of aryl halides with linear alkenes such as pent-1-ene, oct-1-ene or dec-1-ene. Selectivities up to 70% in favour of E-1-arylalk-1-ene isomers can be obtained. In the presence of cyclic alkenes the selectivities of the reactions strongly depends on the ring size. Addition to cyclohexene or cycloheptene led mainly to 1-arylcycloalk-3-ene derivatives. On the other hand, addition to cyclooctene led to 1-arylcycloalk-1-ene adducts.
Tailoring aqueous solvents for organic reactions: Heck coupling reactions in high temperature water

High temperature water is demonstrated to be an effective solvent for Heck coupling reactions of aromatic halides with cyclic alkenes without the addition of co-solvents or specialized ligands. Reactions in the presence of LiCl and quaternary ammonium salts indicate that the reaction takes place in the aqueous phase.
IMPROVED PROCEDURES FOR THE PALLADIUM-CATALYZED INTERMOLECULAR ARYLATION OF CYCLIC ALKENES

Improved procedures for the palladium-catalyzed, intermolecular, allylic crosscoupling of aryl halides and cyclic alkenes inhibit double-bond isomerization and accommodate many important functional groups.
PALLADIUM-CATALYZED INTERMOLECULAR ALLYLIC ARYLATION OF CYCLOALKENES
Larock, Richard C.,Baker, Bruce E.
, p. 905 - 908 (2007/10/02)
Aryl halides and cycloalkenes undergo palladium-catalyzed, intermolecular, allylic cross-coupling in excellent yields under exceptionally mild reaction conditions.
