摘要

Abstract The catalytic decarboxylation of phenyl fluoroformate to fluorobenzene has been achieved with yields of 70–80% in a flow system using alumina or alumina-based catalysts. The reaction occurs in short space times (< 1 s) and with optimal efficiency at ca. 300 C (some 500 C lower than the temperature required for the thermal decomposition of the fluoroformate). Impregnation of the alumina with a platinum group metal gave the ...
