General Procedure
The reaction was carried out by charging a 50-mL round-
bottom flask with 150 mg of catalyst in 5 mL of acetonitrile,
0.48 mmol of the corresponding substrate and the corre-
sponding equivalent amount of hydrazine hydrate with
0.04 mL of 25% aqueous ammonia. The reaction mixture
was stirred at room temperature for the required time at
450 rpm. The reaction mixture was extracted with diethyl
ether (15 mL). The products were analyzed by GC and GC-
MS. The yield was calculated using nitrobenzene as external
standard and determination of the response factor of re-
agents and products with respect to this standard.

tered, washed with diethyl ether (5 mL), dried at 608C for
2 h and reused directly without further purification for the
second run with fresh styrene. It was used for four consecu-
tive runs with a gradual loss in activity.
