Iron can catalyze head-to-head dimerization of terminal aryl alkynes to give the corresponding (E) selective conjugated enynes in high yields. A variety of substituted aryl acetylenes underwent smooth dimerization using catalytic FeCl3 and DMEDA in the presence of KOtBu.
A new efficient tetraphosphine/palladium catalyst for the Heck reaction of aryl halides with styrene or vinylether derivatives

cis,cis,cis-1,2,3,4-Tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C 3H5)]2 system efficiently catalyses the Heck reaction of aryl halides with styrene and vinylether derivatives. High turnover numbers can be obtained for the reaction of several aryl halides with styrene and styrene derivatives. Lower turnover numbers have been observed in the presence of vinylethers.
Studies in the Tricyclooctane Series. VI. Dehydrohalogenation of 8,8-Dihalobicycloocta-2,4-dienes: Plausible Intermediates in the Tricyclooctane-Styrene Conversion
Banwell, Martin G.,Halton, Brian
, p. 2685 - 2691 (2007/10/02)
The dehydrohalogenation of 8,8-dichloro- and 8,8-dibromo-bicycloocta-2,4-diene (4c,d) gives rise to the (E)- and (Z)-isomers of β-t-butoxystyrene (2c).Plausible pathways for the conversion are discussed and evidence in support of bicycloocta-2,4-dienes as intermediates in the conversion is presented.The results support the intervention of halobicycloocta-2,4-dienes in the conversion of tetra- and tri-halo-cis-transoid-cis-tricyclo3,5>octanes (1a-d) to styrenes (2a-c).
