Summary The group VIB metal carbonyls were found to promote the polycondensation of benzyl halides when induced by heat. Their catalytic activity decreases in the order: Mo ≫ W 〉 Cr. Phosphine ligands attached to the metal poison the catalytic activity of the system. Species such as (CO)3M(PhCH 2 + )Cl− are considered to be active in promoting polymerization. The final polybenzyls have a branched, polycondensed structure of moderate molecular weight.
