REGIOREGULAR AND REGIOIRREGULAR SUBSTTUTED POLY (P-PHENYLENE) S BY Ni(0) CATAL YZED DIMERIZATION AND POLYMERIZATION FO ARYLMESYLATES AND ARYLENEBISMESYLATES

摘要

In 1991 we reported two novel methods for the preparation of soluble substituted poly(p-phenylene)s via the Ni(0) catalyzed homocoupling of the substituted p-dichlorobenzenc and of bistriflai.es obtained from substituted hydroijuinones. [1] Alternative methods for the preparation of substituted noly(p-phenylene)s were reviewed both by us [lc], and by others [2]. Synthesis of polyCphcnyleneV. by Ni(0) catalyzed polymerization of various dicliloreticnzene derivatives has received, very rapidly, interest in various laboratories [3].
