Polyphenyl derivativesQ 0700 A Convergent Radical-Based Route to Biaryls. — The method involves radical ad-
dition of alkene (I) to a variety of xanthates accompanied by the 1,2-aryl shift to afford α,β-unsaturated esters. They are further treated with DBU under microwave conditions to yield the target biaryls. Ring closure of (IX) and (XII) proceeds with loss of the methoxy group. — (QUICLET-SIRE, B.; REVOL*, G.; ZARD, S. Z.; Org. Lett. 11 (2009) 13, 2832-2835; Lab. Synth. Org., CNRS, Ec.
