1,6-Diynes, possessing aryl groups on their termini, undergo an intramolecular [4+2] cycloaddition via strained cyclic allene intermediates to give various biaryl compounds. Under thermal conditions, isomerization of the intermediates occurs, while, in th

Potassium alkoxides undergo anti-Markovnikov addition to aryl-substituted alkynes with Z selectivity in DMF as the solvent. The yields and efficiency of the reaction was also found to be enhanced by the addition of a secondary amine ligand such as N,N′-di

(Chemical Equation Presented) Catalytic cyclization of 1,6-allenynes was achieved by AuPPh3SbF6 (5 mol %) in cold CH 2Cl2 (0°C, 0.5-4 h) to form bicyclo[4.3.0]nonadiene products; this cyclization proceeded more

We report a new efficient intramolecular [3 + 2]-cycloaddition of unactivated arenyne (or enyne)-yne functionalities, catalyzed mainly by the AuPPh3SbF6 complex (2 mol %) under ambient conditions. The value of this cyclization is ref
