摘要:已测量甲基,乙基,正丙基,异丙基,叔丁基和新戊基氯化物和溴化物与以下亲核试剂的气相反应的速率系数,按碱度递减的顺序列出:Ho-,Ch 3 O-,F-,Ho-(H2O),Cf 3 CH2O-,H 2 Ns-,C 2 F 5 CH2O-,Hs-和cl-.对于氯甲烷,反应效率首先显着低于 1,以 Ho-(H2O) 作为亲核试剂,而对于甲基溴,以 Hs-作为亲核试剂;在这两种情况下,总反应放热度约为 30 Kcal Mol-1 .这些卤化物与强碱反应缓慢的早期结论被证明是错误的.在速率较慢的区域,氧阴离子通过消除与烷基氯化物和溴化物反应,而相同碱度的硫阴离子通过取代反应.这种差异是由于硫碱的消除速度减慢;与相同碱度的氧阴离子相比,硫阴离子没有增加亲核性

标题 :Systems and methods for preparation of highly reactive alkali metal dendrites for the synthesis of organolithium reagents

摘要:Systems and methods for formation of highly reactive alkali dendrites are provided. For example, in some embodiments alkali metals are dissolved in ammonia to form metal electrides after which the ammonia is removed via vacuum to reveal highly activated metal surfaces in the form of crystalline alkali dendrites. The alkali dendrites can mimic powders but have the advantage of being freshly prepared from inexpensive and readily available metal sources. These uniquely activated metals exhibit enhanced reactivity comparatively to similar off the shelf sources of the corresponding metals. For example, the dendrites can have about 100 times greater surface area than conventional metal sources and/or be about 19 times more reactive than powders that serve as the industry standard for the preparation of organometallic compounds. After surface activation, these metals can be used to prepare various organometallic reagents.

标 题 :An improved synthesis of tetrakis (dihydro carbylamino) phosphonium halides

权利人:ALBEMARLE CORP
摘要:An improved, commercially viable process for synthesizing tetrakis(dihydrocarbylamino)phosphonium halides in the absence of oxigen is described. When reacting a tris(dihydrocarbylamino)phosphinimine with a halohydrocarbon and an aqueous solution of a source of hydroxide ion to form a tetrakis(dihydrocarbylamino)phosphonium halide, a combination of increased pressure and liquid organic medium is used. The advantages gained by operating in this fashion include shorter reaction times and the need for only about stoichiometric or slightly more than stoichiometric amounts of halohydrocarbon and source of hydroxide ion.
