All of the preformed catalysts used in the kit are air and moisture stable complexes in their commercially available form. Once activated by base under the reaction conditions they become sensitive to air. To best enable scale-up success, the use of standard Schlenk technique is recommended.
Preformed catalysts in the kit are stable but become air-sensitive when activated; Schlenk technique aids scale-up.
