(2) GW Griffin, AF Marcantonio, H. ICristinsson, RC Petter-son, and CS Irving, Tefrahedron Letr., 2951 (1965).(3) JJ Brophy and GW Griffin, ibid., 493 (1970).(4) Recently, JW Wilson and KL Huhtanen (Chem. Commun., 454 (1968)) described the photochemical rearrangement of methyl 3, 3, 3-triphenylpropyne carboxylate (i) to the indenophenanthrene (iv). The diradical species ii was proposed as a possible intermediate leading to the ...
