Regioselective [2 + 2 + 2] cycloaddition of a nickel-benzyne complex with 1,3-diynes.

Kimberly R Deaton1, Mary S Gin.   

Abstract

[reaction: see text] Reactions of nickel(0)-benzyne complexes with a range of symmetrically substituted 1,3-diynes in the presence of triethylphosphine lead to the regioselective formation of 2,3-dialkynyl naphthalenes. The regioselectivity can be reversed when the diyne possesses substituents of high steric bulk, allowing selective formation of either symmetric dialkynyl naphthalene.
