catalyzes the reductive N-alkylation of aryl nitro compounds with alcohols by a borrowing-hydrogen strategy to afford the corresponding imine products in good to excellent yields. In the absence of xantphos, the [Rh(COD)Cl]2/Cs2CO3 catalytic system behaves as an effective catalyst for the dehydrogenative coupling of alcohols to esters, with nitrobenzene as a hydrogen acceptor. The reactivity of the
[Rh(COD)Cl] 2 / xantphos / Cs 2 CO 3系统通过借位氢策略有效催化芳基硝基化合物与醇的还原性N-烷基化,从而以良好或优异的收率提供相应的亚胺产品。在不存在黄药的情况下,[Rh(COD)Cl] 2 / Cs 2 CO 3催化体系可作为醇与酯脱氢偶联的有效催化剂,硝基苯为氢受体。铑催化体系的反应性可以很容易地控制以选择性地提供亚胺或酯。

Surface-modified polymer films for coating are provided, wherein the surface is modified by covalent binding of nano- or micro-particles comprising a photoreactive species. The surface of the polymer film, e.g. a parylene film, may be modified by covalent binding of nano- or micro-particles of a polymer, e.g. a conductive bifunctional polymer further comprising a chemically reactive functional group, or of a hybrid organic-inorganic oxide, e.g., silica, network comprising a photoreactive species. Further provided are: (i) polymerizable monomers, the conductive bifunctional polymers obtained therefrom; (ii) a hybrid photoreactive organic-inorganic oxide network; and (iii) micro- or nano-particles made from (i) or (ii).
