Pyridinium and diazinium dicycanomethylides underwent 1,3-dipolar cycloaddition-extrusion reactions with phenylsulfinylethene, producing the corresponding 3-cyanoindolizines in moderate to good yields. 1,3-Dipolar cycloadditions of these ylides with bis(t
1,3-DIPOLAR CYCLOADDITION OF PYRIDINIUM AND DIAZINIUM DICYANOMETHYLIDS WITH BIS(TRIMETHYLSILYL)ACETYLENE: SYNTHESIS OF TRIMETHYLSILYL SUBSTITUTED INDOLIZINES AND BIS(TRIMETHYLSILYL)ACETYLENE AS AN ACETYLENE EQUIVALENT IN 1,3-DIPOLAR CYCLOADDITION

Cycloaddition reactions of pyridinium and diazinium dicyanomethylids with bis(trimethylsilyl)acetylene give either the corresponding 1,2-di(trimethylsilyl)-3-cyanoindolizines or the mixtures of these and 1-(trimethylsilyl)-3-cyanoindolizines depending on
