Unless otherwise stated, all operations are carried out in flame-dried glassware under an inert gas atmosphere using standard Schlenk techniques.6

Solvents were dried over sodium (light petroleum, bp 40-60°C, toluene) or sodium-benzophenone (diethyl ether, THF). Sodium amide, hexamethyl-disilazane, lithium triethylhydroborate(l —), and hydrogen tetrafluoro-borate(l —) diethyl ether complex were obtained from Aldrich and used as supplied. 

Bis(bis(trimethylsilyl)amido) complexes of zinc and cadmium are thermally stable but highly sensitive to hydrolysis and must be manipulated under inert gas.
