the WINGX software. The non-hydrogen atoms were refined
anisotropically, while the hydrogen atoms were placed with fixed
thermal parameters at idealized positions. The perchlorate anion
in 2 was disordered. Perspective views of the molecules are given
in Fig. 2 and 3.

taken in a 100 mL stoppered conical flask. To the above
solution, 1.0 mL aqueous solution of KBr (0.22 g, 1.84 mmol)
and 1.0 mL (9.80 mmol) of 30% H O were added under stirring

was stirred continuously at room temperature for 20 h for the
completion of the reaction. Thereafter, the products were
quantitatively extracted with diethyl ether (2.0 mL) so that
practically the entire reaction product was transferred to the
ether layer. Then the ether extract was concentrated to B1.0 mL
by slow evaporation and from the extract, 1.0 mL of the solution
was taken in a gas syringe and injected through a GC port. The
products were characterized by gas chromatography (Agilent

complex 2 (the catalyst) except that complex 2 was used instead
of complex 1.
