摘要:Methods are provided for preparing aromatic silicon-containing compounds. The methods include providing an aromatic starting material; reacting the aromatic starting material with a base to form an aromatic salt; and reacting the aromatic salt with a halo-alkylene-silane to form an aromatic silicon-containing compound. Compositions prepared by these methods, protective layers that include hydrolysis and condensation products of such compositions, electrophotographic photoreceptors that include such protective layers, and image forming apparatuses that include such electrophotographic photoreceptors are also provided. In addition, method for preparing electrophotographic photoreceptors that include protective layers including hydrolysis and condensation products of aromatic silicon-containing compounds prepared by the methods for preparing aromatic silicon-containing compounds are provided.

发明人：MURPHY LEANNE DAWN
权利人:XEROX CORP
摘要:Processes for selectively hydrogenating double and/or triple bonds in organic molecules include providing at least one organic molecule containing a double and/or triple bond, providing at least one hydrogen donor molecule, and hydrogenating the double and/or triple bond in the presence of at least one catalyst. Processes for preparing arylamine molecules include selectively hydrogenating double bonds in arylamine compounds by providing at least one organic molecule containing a multiple bond, providing at least one hydrogen donor molecule, and hydrogenating the multiple bond in the presence of at least one catalyst. The processes provide efficient, cost-effective and safe methods for conducting selective hydrogenation reactions in the synthesis of organic molecules, such as charge-transport molecules.

摘要:Synthesis of hyperbranched-linear-hyperbranched ABA triblock copolymers based on linear poly(oxy methylene) (POM) and hyperbranched poly(glycerol) (hbPG) blocks is described. The polymers having a polyacetal polyether structure were prepared from linear bishydroxy functional POM macroinititators, obtained by cationic ring-opening polymerization of trioxane and dioxane with formic acid as transfer agent and following hydrolysis of the formiate group. Partial deprotonation of the resulting hydroxyl groups permitted the hypergrafting by anionic ring-opening multibranching polymerization (ROMBP) of glycidol.
