This paper reviews the advances during the passed years on synthesis of five patterns of insolube polymer - supported phase transfer catalyst using onium salts
crown ethers & cryptants
polyethylene glycol catalyst using onium salts
crown ethers & cryptants
polyethylene glycol (PEG)& its derivates
cosolvents and optically active quaternary ammonium salts as their active site respectively
and presents the characteristic of some of them.
