Sterically Hindered Free Radicals, XVI. The Existence of Tetraphenylsuccinic Acid and Its Esters, and the Structure of the Dimers of the Diarylmethyl Radicals Ar2C*-X, X = CO2R, CN, COR

All syntheses of tetraphenylsuccinic acid (esters) described in the literature in fact yield the quinonoids 5 or, after a 1,5-H shift, the benzoids 6. 5 dissociates reversibly giving the radicals Ph2C*-CO2R 4.A real succinic acid derivative, 9, arises, ho
