Abstract

The p-bromo compound was converted into the corresponding cyano and methoxy compounds (IC and Id, respectively) by use of copper-catalyzed displacements."(b) Preparation of% arrangement Products. In principle, four rearrangement products can be derived from each 1-(pX-phenyl)-1-phenylindene on successive 1, 5 phenyl and hydrogen shifts. These are, of course, 3, 4, and the corresponding A'$ isomers;'* however, in practice ...
