Abstract
Transformation of O-vinylacetophenone oxime in the system (BuOK)-O-t-T HF was studied. The reaction at 60-65 degrees C was shown to afford no t the anticipated 2-phenylpyrrole, but, instead. 2,4-diphenylpyrrole ( 21% yield) and oligomer products (40% yield). The latter have the same elemental composition as the starting O-vinyl oxime but do not contai n vinyloxy groups or pyrrole fragments.
