Three N-phenacyl-γ-trimethylsilyl (triphenylsilyl)pyridinium bromides were converted to stable silyl-substituted pyridinium ylids. Six previously unknown silicon-containing indolizines were obtained by two methods, viz., 1,3-dipolar cycloaddition of dimethyl acetylenedicarboxylate (DMAD) to the pyridinium ylids and the Chichibabin reaction. Spectral data that confirm the structures of the synthesized compounds are presented. © 1981 Plenum Publishing Corporation
