摘要

2, 5-Disubstituted pyrroles react with carbon disulfide in the system KOH–DMSO with selective formation of pyrrole-3-carbodithioate anions from which pyrrole-3-carbodithioates were prepared by ethylation in 36–61% yield. From 2-methyl-5-phenyl (2-furyl-or 2-thienyl) pyrroles only pyrrole-3-carbodithioates are formed, with no isomeric pyrrole-4- carbodithioates being present. The reaction direction depends on pyrrole ring substitution: ...
