Simple, tunable aziridination catalysts based on poly(pyrazolyl)borate-copper complexes.

[reaction: see text] The in situ generation of a copper-poly(pyrazolyl)borate complex from copper chloride and a sodium poly(pyrazolyl)borate salt results in a catalyst that is effective for the aziridination of olefins. A significant influence of the combination of the starting copper oxidation state and the hapticity of the poly(pyrazolyl)borate ligand on the efficiency of the reaction has been observed.

Organic synthesis in ionic liquids: the Stille coupling.

[figure: see text] The Stille coupling reaction has been performed in 1-butyl-3-methylimidazolium tetrafluoroborate (BMIM BF4), a room-temperature ionic liquid (RTIL). Use of this solvent system allows for facile recycling of the solvent and catalyst system, which can be used at least five times with little loss in activity. An interesting preference in starting catalyst oxidation state for use with aryl bromides and aryl iodides was observed.
