For the purpose of synthesizing heat-resistant polyesters, the one-step synthesis of a rigid biphenyl-containing polyester from dihalobiphenyl and diol by palladium-catalyzed carbonylation-polycondensation was examined.The reaction parameters, such as the

Palladium on charcoal was found to catalyze the carbonylation of aryl iodides with various aliphatic alcohols as well as less reactive phenols to give the corresponding esters in high yield at 140°C and in the presence of carbon monoxide (1.0 MPa). The carbonylation-polycondensation of 2,7-diiodo-9,10-dihydrophenanthrene with bisphenol-A afforded high molecular weight polyarylate, poly [oxy-1,4-phenylene (1-methylethylidene)-1,4-phenyleneoxycarbonyl (9,10-dihydro-2,7-phenanthrenediyl) carbonyl].
