Abstract

Diarylmethanes 1a-h, 9a-i and 12 containing a heterocyclic group attached to the central carbon atom have been synthesized. Lithiation of these substrates followed by the addition of iodine gave dimers 2a,b,d,e and 10 via α, para-dimerization of novel heterocyclic diarylmethyl radical intermediates.
