Synthesis of benzo-fused five- and six-membered heterocycles by palladium-catalyzed cyclocarbonylation
摘要:
A novel and simple synthetic methodology, based on palladium-catalyzed cyclocarbonylation reaction, is presented for preparing five- and six-membered benzo-fused heterocycles. A mechanism for the process is also proposed and discussed. (C) 2011 Elsevier Ltd. All rights reserved.

Polycarbonates are provided exhibiting anisotropic properties in the melt. Transesterification of diphenylcarbonate is effected in the melt with a mixture of methylhydroquinone and 4,4′-dihydroxybiphenyl. The polycarbonates are found to be insoluble in several common solvents such as chloroform, methylenechloride, and toluene.
