Abstract

Abstract: The zero-valent nickel complexes, which are generated in situ from nickel (I1) complexes by reduction with zinc, have been found to catalyze the cyclooligomerization of butatrienes, 2, 3-dihalo-1, 3-butadienes, 1, 4-dichloro-2-butyne, and 1, l-dibromoethylene to give the corresponding [4]-and [6] radialenes. The formation of the [4]-and (6lradialenes depends on the reaction conditions, especially on solvent, and each product of the ...
