    • The Scholl precursors in Figure lincluding hexaphenylbenzene derivatives do not undergo any cyclization reaction when exposed to various protic and Lewis acids (Scheme 1) without DDQ for extended periods (up to ∼24 h) and the starting precursors can be recovered quantitatively by treatment with aqueous sodium bicarbonate. Similarly, various Scholl precursors did not show any reaction when exposed to DDQ alone in dichloromethane at 22 °C for 24 h
