✦ Synopsis

Most early largely derived attempts to generate 2,2,2_triphenylethyl radical (I_) led either to products from its rearrangement to 1,1,2-triphenyletbyl radical (ZZ)l or to failure to form it. 2 However, Kaplan3 observed both rearranged (2) and unrearranged ()+) triphevlethanes during reduction of 2,2,2_triphenylethyl chloride (2) with triphenyltin hydride (6a). Rearrangement was promoted by decreasing [&I 4 and increasing temperature. Hydrocarbons ,j and 5 were formed in comparable amounts et 100" with [&_a] _ 1% from which observation Csrlsson
