Treatment of 2-hydroxyazulene (la) with 3 equiv. of C 5 H 5 N·HBr 3 in aqueous THF-AcOH at 0 °C for 1 h afforded l,l,3-tribromoazulene-2-one (5a). 3-Bromo-l,2-azulenequinone (2a) was obtained by the hydrolysis of 5a in the presence of Ag 2 O. Annul

A new type of redox-responsive molecular rotors (3 2+ /4) possessing a xylyl rotator unit have been designed and synthesized. Reduction of 3 2+ with zinc gave the corresponding cyclization products (4), from which dications (3 2+ ) were regenerated u

In order to develop new redox systems which undergo reversible structural changes by electron transfer, bis(1,3-benzodithiolium)-type dications (5 21) containing a biaryl unit have been synthesized by hydride abstraction of the corresponding bis(1,3-
