摘要:尽管有机膦的合成在一个世纪的上半叶已广为人知,但是即使对于资深的合成化学家来说,膦的合成仍然代表着艰巨的任务.膦作为一类化合物,其对空气的敏感性差异很大,并且误以为新手化学家尝试看似简单的合成是微不足道的,甚至是容易的,这会带来灾难性的结果.为了简化任务,我们之前已经开发出一种使用台式中间体访问各种氧化膦(膦的直接前体)的方法.这种合成方法可以节省无空气的处理,直到最后一步(还原并分离出膦).本文介绍了将膦酸酯,次膦酸酯和膦氧化物轻松还原为伯,仲,和叔膦使用氢化铝还原剂.亲电还原剂(i Bu) 2 Alh和alh 3在还原选择性和反应性方面被确定大大优于lialh 4.值得注意的是,即使lialh 4和(I Bu) 2 Alh不能,Alh 3仍能还原具有极强抗性的三环己基氧化膦.使用这种新方法,可以以克级反应合成出代表性范围的伯,仲和叔膦(包括挥发性膦),而无需纯化步骤,可实现出色的收率和无与伦比的纯度.

标题 :Method for synthesis of colloidal nanoparticles
发明人：STROUSE GEOFFREY FIELDING; GERBEC JEFFREY A; MAGANA DONNY
权利人:UNIV CALIFORNIA
摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

标 题 :Rhodium based catalysts for the synthesis of 1,4-dienes
发明人：SU A
权利人:DU PONT
摘要:Improved catalysts are provided for the synthesis of 1,4-dienes from Alpha -monoolefins and conjugated dienes. The catalysts are rhodium (III) salts in combination with amides, phosphoramides, phosphine oxides, or water. The improved catalysts allow control of the trans-cis ratio of the 1,4-diene formed and are operable at useful rates in a wide range of solvent systems, both protonic and aprotic.

摘要:The present invention is directed to a condensed phase batch process for synthesis of trisilylamine (TSA). An improved synthesis process that incorporates a solvent to help promote a condensed-phase reaction between ammonia gas (or liquid) and liquified monochlorosilane (MCS) in good yields is described. This process facilitates the removal of the byproduct waste with little to no reactor down time, substantial reduction of down-stream solids contamination and high-purity product from first-pass distillation.

标 题:A method for the synthesis of tris(ortho-carboranyl)borane
发明人：Martin Caleb; AKRAM MANJUR
权利人:UNIV BAYLOR
摘要:The described process synthesizes a halide-free single-site borane compound product tris( ortho -carboranyl)borane, or B o Cb 3 . B o Cb 3 has Lewis superacid properties. The compounds, B o Cb 3 , are thermally stable, and not reactive towards oxygen, but are sensitive to water. The characteristic high fluoride ion affinity is further translated to the catalytic C-F bond activation reactions of the unactivated alkyl fluorides towards the reduction and C-C bond forming reactions with silanes, and Fridel-Crafts type reactions with arenes. The potential of the synthesized Lewis acid as a catalysis is anticipated.

标题 :Synthesis of aliphatic 1,3-diols utilizing reduced ligand concentration and water extraction

摘要:This invention is a process for synthesizing aliphatic 1,3-diols in one step by hydroformylation and hydrogenation of oxirane, carbon monoxide, and hydrogen employing a catalyst comprising a cobalt carbonyl compound and a cocatalyst metal compound ligated with a ligand in a ligand to cocatalyst metal atom molar ratio in the range of 0.2:1.0 to 0.6:1.0, optionally in the presence of a promoter, where recovery of product is preferably accomplished via water extraction of a diol rich phase from the bulk reaction mixture. The process modifications can, particularly in combination, be beneficial with respect to product recovery, catalyst recycle, and overall economics of a one-step process for producing aliphatic 1,3-diols.
