Abstract: The reactions of o-halobenzoic acids, dichloromethane and potassium hydroxide providing benzo[d][1,3]dioxin-4-ones have been realized via the catalysis of Cu(OAc)2. Tandem Ar–X (X = I, Br) bond hydroxylation and double Williamson etherification on dichloromethane are involved… read more here.

Abstract: Poly(methyl methacrylate) (PMMA) and poly(ethylene glycol) methyl ether (mPEG)-based monotelechelics were quantitatively prepared by copper (I)-catalyzed azide/alkyne cycloaddition (CuAAC) click reactions using azido-terminated polymers and alkyne functional benzodioxinones. The monotelechelic containing dimethyl moities (2,2-dimethyl-5-(prop-2-yn-1-yloxy)-4H-benzo[d][1,3]dioxin-4-one) was… read more here.
