标题:钌配合物催化甘油氢解制乙酸丙酯
摘要:Ru配合物已被用作在温和条件下甘油氢解的催化剂前体,这产生了乙酸丙酯(pa)作为主要产物.值得注意的是,乙酸与甘油的酯化反应可以防止甘油聚合.In(otf)3在促进甘油的酯化和顺序脱水中起关键作用,而ru络合物的功能是氢化.助催化剂(fecl 3)可以抑制ru络合物还原成ru颗粒,提高催化性能.本发明的催化体系可提供完全的甘油转化和57%的pa收率.最后,据此提出了反应途径.

摘要:The present invention disclose novel process for synthesis of 1,4- dihydronicotinamide riboside (NRH). More particularly, the invention discloses a cost-effective synthesis of 1, 4-dihydronicotinamide riboside (NRH) from Nicotinamide-beta-riboside triacetate chloride (NRA-CI) in good yields and purity comprising the steps of a) reducing Nicotinamide-beta-riboside triacetate chloride (NRA-CI) in presence of non-chlorinated aprotic organic solvent and a reducing agent to obtain 1,4-dihydronicotinamide riboside triacetate (NRH-A); and b) deacetylating the 1,4-dihydronicotinamide riboside triacetate (NRHA) in presence of a base to obtain 1,4-dihydronicotinamide riboside(NRH)

发明人：GHELFI FRANCO; FERRANDO ANGELO; LONGO ALDO; BUFFAGNI MIRKO
权利人:VERSALIS SPA
摘要:The present invention relates to a polymerization process for the synthesis of vinyl aromatic polymers, in which the sequence of monomers in the chain and the linear, branched soluble, or crosslinked insoluble structure, with reactive or different polarity functions, are controlled. Said process comprises the step of polymerizing vinyl aromatic monomers by means of an Atom Transfer Radical Polymerization (ATRP) reaction with an Activator ReGenerated by Electron Transfer (ARGET), the reaction being carried out at a temperature comprised between 25° C. and 110° C. in an inert gas atmosphere in the presence of a complex catalyst containing a cupric halide and a multidentate amine ligand, feeding to the reaction an organic initiator having two geminal halogens, an alkali metal (bi)carbonate, a solvent pair of an aliphatic alcohol and an acetic ester of the same aliphatic alcohol and possibly ascorbic acid, provided that no initiator is used with three or more active halogens, or polyvinyl monomers or inimers.
