9. 2O in MeCN. In both cases, the reaction mixture was stirred at room temperature for 4-5 h. The precipitates obtained were filtered and washed with diethyl ether and dried in air.
10. 2 (1 equiv) in MeCN the catalyst 1 or 2 (0.1 or 0.03 equiv, respectively) was added. The procedure outlined above was then followed.
