PREPARATION AND PROPERTIES OF POLYMERS ANCHORING BIPHENYL-2-OL.

The monomer, 2-biphenyl acrylate (BPA) was prepared and was polymerized and copolymerized with vinyl acetate (VAc), styrene and N-vinylpyrrolidone. The reactivity ratios of BPA(M//1) with VAc were evaluated as r//1 equals 4. 6 plus 0. 4 and r//2 equals 0. 37 plus 0. 08. The polymers were hydrolyzed in methanol-phosphate buffer solution (pH 6 and 8), and the release rate of biphenyl-2-ol from the polymer was investigated. The biphenyl-2-ol could thus be employed as a fungicide over an extended period.

An extremely efficient and green method for the acylation of secondary alcohols, phenols and naphthols with a deep eutectic solvent as the catalyst

The typical deep eutectic solvent [CholineCl][ZnCl2]3, easily prepared from choline chloride and zinc chloride, is green and useful for the acylation of secondary alcohols, phenols, and naphthols with acid anhydrides. Its efficiency allows the acylation of sterically hindered secondary alcohols and acid anhydrides to proceed in high yield under mild condition. The catalyst is cheap, easy to handle, conveniently synthesized in a single step, and recyclable for several times without significant loss of catalytic activity.

Enzymatic Esterolysis of Polymers Containing 2-Biphenylyl Ester Bonds in Side Chains

The preparation and α-chymotrypsin-catalyzed esterolysis of polymeric substrates anchoring fungicidal biphenyl-2-ol are described.In order to obtain information regarding the influence of one type of polymeric backbone and the distance between a cleavable bond and a polymer main chain, poly(2-biphenylyl acrylate), poly(2-biphenylyl methacrylate), and poly(methacryloylamino acid 2-biphenylyl ester) were studied.The esterolysis were evaluated by means of Michaelis constant Km and the catalytic reaction rate constant kcat.Poly(2-biphenylyl methacrylate) was a more suitable substrate than poly(2-biphenylyl acrylate).Poly was the most suitable substrate in a series of polymers containing amino acid side chains with 2-biphenylyl ester terminal groups.The release rate of biphenyl-2-ol could also be controlled by using copolymers with an appropriate comonomer.
