Polyisobutylene supports—a non-polar hydrocarbon analog of PEG supports

Synthetic routes to terminally functionalized polyisobutylene oligomers useful as supports in synthesis and catalysis are discussed and described. Such hydrocarbon polymers serve as highly soluble non-polar analogs of well known poly(ethylene glycol) supports for synthesis and catalysis with the difference that they are separated after a reaction by an extraction with alkane solvent.
