The development of catalysts for the efficient oxidation of catechol and its derivatives in water is topic of ongoing work in this laboratory. Towards this end, polyethylene glycol side-chains were incorporated in a pentadentate salen ligand to enhance the water solubility of the complexes derived thereof. A dinuclear copper(II) complex is found to catalyze the oxidation of 3,5-di-tert.-butylcatechol into 3,5-di-tert-butyl-o-benzoquinone more than twice as fast in aqueous organic solution as in purely organic solvents (ly,at/knon= 140,000). Preliminary data are discussed. [Pg.473]

In our ongoing efforts to develop oxidation catalysts that are functional in water as environmentally berrign solvent, we synthesized a water-soluble pentadentate salen ligand with polyethylene glycol side chairts (8). After coordination of copper(II) ions to the salen ligand, a dinuclear copper(II) complex is obtained that is soluble in water, methanol and mixtures of both solvents. The aerobic oxidation of 3,5-di-tert.-butylcatechol (DTBC) into 3,5-di-terr.-butylqitinone (DTBQ) was used as a model reaction to determine the catalytically active species and initial data on its catalytic activity in 80% methanol. [Pg.473]

An efficient one-pot synthesis of isoxazolines, using soluble polymer-supported acrylate has been described (174). Thus, the addition of 1,4-benzenedicarbonitrile N,N -dioxide (generated from N, N -dihydroxy-1,4-benzenedicarboximidoy 1 dichloride) to polyethylene glycol-supported 2-propenoic acid 2-hydroxyethyl ester 32 (P = polyethylene glycol support) followed by cleavage of the bond with the support gave 3,3/-(l,4-phenylene)bis[4,5-dihydro-5-isoxazolecarboxylic acid] di-Me ester (33) in 97% yield. [Pg.22]

Ng [2,3] prepared bioerodible copoly(ortho esters) consisting of the Step 2 product with monomethyl polyethylene glycol ether termini and 1,4-cyclohex-anedimethanol and either an a-hydroxy carboxylic acid, (II), or A -methyl-di-ethanol amine (III), for use as bioerodible matrices for the sustained release of biologically active agents. Other dioxalane bioerodible analogues were prepared by Ng [4] in an earlier investigation. [Pg.63]
