A reaction which is reminiscent of the Wurtz coupling procedure, and which is particularly valuable in the syntheiss of biphenyl and its symmetrically substituted derivatives, is that of Ullmann. It involves heating an aryl halide with copper powder, or better, with activated copper bronze. [Pg.835]

The Wurtz and Ullmann couplings of organic halides are usually carried out with alkali metals in ethereal solvents, or copper in a high-boiling solvent, commonly DMF. Surface phenomena occurring on the metal and the existence of radical intermediates were evidenced in the reaction of iodobenzene with copper.194... [Pg.207]

This method yields fairly high MWt P(PP) with little crosslinking. In theory, any of die standard organic aryl coupling reaction, such as the Ullmann, Grignard, Wurtz-... [Pg.409]
