Phase-selective soluble polymer supports for catalysts are described. The catalysts utilize polystyrene copolymers having enhanced solubility in nonpolar solvents. Other catalysts of the invention utilize polyisobutylene supports. Methods of catalyzing chemical reactions using latent biphasic solvents are also disclosed.

[reaction: see text] Use of soluble poly(4-tert-butylstyrene) (PtBS) as a support in synthesis is demonstrated. These solublepolymerssupported catalysts that were used in a monophasic medium. Subsequent separation of the catalysts after reaction was effected either by cooling- or by water-induced liquid/liquid-phase separation. Specific catalysts studied included both phosphine and DMAP nucleophilic
