The transylidation reaction of methyl(triphenylphosphoranylidene)acetate with 2-chlorocyclohepta[b]pyrrole derivatives has been studied. 3,8-Disubstituted derivatives gave a transylidation product only, whereas 3-substituted derivatives afforded not only a transylidation products but also the compounds formed by the addition of ylide at C-8. ^<13>C NMR spectra of the transylidation products are recorded in part
