The shape-selective alkylation of polycyclic hydrocarbons is used to synthesize symmetric intermediates such as 4,4′-dialkylbiphenyl (4,4′-DABP) and 2,6-dialk
Diphenyl carbonate (DPC) is a basic material for non-phosgene production of polycarbonates. Several alternative non-phosgene methods for DPC synthesis have also
