Abstract

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.
