Stereoselective syntheses of deuterium labelled marmesins 3a-3e as metabolic probes for biosynthetic studies are described. Starting from iodo-umbelliferone (5), the title compounds were readily available by copper catalysed alkylation-cyclisation and subsequent transfer-hydrogenation of the resulti
## Abstract The mechanism of the electrochemical polymerization of pyrrole and pyrroleβ__d__4 has been studied by an examination of the kinetic deuterium isotope effect. The kinetic rate constants of the reaction were measured by cyclic voltammetry, UV/visible specrophotometric analysis of polymer
