Abstract

Bis [10-(4-t-butyl-2, 6-dimethylphenyl)-9-anthryl] diazomethane, which can generate a fairly stable triplet carbene that can survive for even a week in solution at room temperature, was shown to be stable enough to undergo a Sonogashira coupling reaction. Thus, three units of the diazo compounds were connected through an ethynyl group on 1, 3, 5-positions of benzene. The species generated by irradiation of the resulting tris (diazo) compound were ...
