It has been established that the dienylation of unfunctionalized arenes with 1,6-diynes, possessing aryl groups at the diyne termini, proceeds to give the corresponding dienylated arenes in the presence of a catalytic amount of an electron-deficient cyclopentadienyl rhodium(III) complex, [Cp ERhCl 2] 2, and a stoichiometric amount of silver carbonate. Experimental and theoretical mechanistic studies revealed that a Cp ERh(I) complex generated in situ might catalyze the present dienylation- reaction.
O-Dihaloarenes as aryne precursors for nickel-catalyzed [2 + 2 + 2] cycloaddition with alkynes and nitriles

supporting information; experimental part, p. 2992 - 2994 (2009/02/04)
o-Dihaloarenes acting as aryne precursors react with acetylenes and nitriles catalyzed by the NiBr2(dppe)/dppe/Zn system to give substituted naphthalene, phenanthridine or triphenylene derivatives depending on the reaction conditions in moderat
