Schlenk-type reaction/filtration flask

A Schlenk-type apparatus, illustrated in Fig. 1, is used for the synthesis. This apparatus is similar to that employed in other syntheses but allows for multiple filtrations of the reaction solution and manipulation of the complex in a completely sealed system. In a nitrogen glove box, a 100-mL round-bottomed flask (B) is charged with 1.0 g (9.4 nunol) of palladium sponge (99.95%, Johnson Matthey) and 2.2 g (18.8 mmol) of nitrosyl tetrafluorobor-ate (Aldrich, sublimed 220°C, 10 torr). This flask is connected to a medium...
