Preparation of a novel soluble multi-site phase transfer catalyst and the kinetic study for the C-alkylation of α-pinene

Novel soluble “multi-site (6 site)” phase transfer catalyst viz.1,3,5-tris(4-(2,2′-bis(N-triethylammoniummethylene chloride)eth-1-ene)phenoxymethyl)benzene (TBTEAPB) has been prepared by a simplified method and characterized. It is shown to be ≅6 and 3 times as effective as single-site and di-site PTCs respectively in catalyzing the C-alkylation of α-pinene with epichlorohydrin.
