ChemInform Abstract: Reactions of 1,1‐Diphenylethylene and Its Derivatives with Tris(p‐bromophenyl)aminium Hexachloroantimonate.

Abstract

ChemInform Abstract 1,1-Diphenylethylene (Ia) undergoes radical-induced dimerization in the presence of aminium hexachloroantimonates to give the indan (II). Addition of water to the reaction mixture results in the formation of the tetraphenylbutadiene (IIIa) and the tetrahydrofuran (Va). The analogous reaction with (Ib) -(Id) yields (IIIb) -(IIId) and the tetraarylcyclobutanes (IVc) and (IVd).
