Rasta resin-PPh3BnCl, a heterogeneous polystyrene-based phosphonium salt, catalyzes cyanosilylation reactions of aldehydes and ketones efficiently. In these reactions, rasta resin-PPh3BnCl was separated from the desired reaction product simply by filtration, and it could be reused without significant loss of catalytic activity numerous times.
