Abstract

Due to the ease of their preparation3p4 and to their high reactivity5i6 a-(chloromethy1)-and w (bromomethy1)-pyrroles are valuable intermediates for the synthesis of a number of pyrrole derivatives with functionalized CY side chains. They have also been extensively used in alkylation reactions leading to dipyrrylmethanes,'dipyrrylmethenes? and more complex polypyrrolic systems derived therefrom. Apart from a few papers dealing with the ...
