The chemistry of pyrrolic compounds. XIX. Reactions of pyrrolic compounds with orthoformates

Abstract

A mixture of triethyl orthoformate and trifluoroacetic acid has been developed as a means of formulating certain pyrroles and dipyrrylmethanes. The advantages and disadvantages of the procedure are discussed. The use of p-toluenesulphonic acid with orthoformate converts pyrroles into tripyrrylmethanes.
