BH3-THF络合物 体系反应 1,3-Di(hydroxymethyl)-2-nitrobenzene: 1,3-Dicarboxylic acid-2-nitrobenzene (2.50 g, 11.8 mmol) was dissolved in THF (12.5 mL) and cooled with an ice bath. 1M Borane-THF (59.0 mL, 59.0 mmol) was then added dropwise and the reaction was stirred for 48 hours. ...
3-Methylisoxazolo[4,5-c]pyridine on reduction with BH3:THF gave, via the isolable complex , the tetrahydroisoxazolopyridine . The presence of two chlorine atoms at the 4 and 6 positions directed borane attact to the isoxazole ring, yielding the aminoethylpyridine . Both types of reduction ...
The novel arachno-2-tungstametallaborane, [WH 3(PMe 3) 3B 3H 8[, has been made in high yield (>90%) by the reaction of the monoborane BH 3·THF (THF = tetrahydrofuran) with [WH 6(PMe 3) 3]. This represents a controlled transition metal mediated synthesis of a higher borane moie...
Four-membered Rh-N-B-H metallacycles [Rh{(mu-H)BH2)(Ntrop(2))(L)] (L = PPh3, IMe) were isolated by direct reaction of the amide complex with BH3(THF). These stable species are not active in the dehydrogenation of DMAB. Their isolation and lack of reactivity gives some ...
在THF 的建筑群的不能解决性然后允许我们冲毁过多的 DABCO 和 DABCO-BH3。加固体 ( Pd(?(3-allyl) Cl )2 到接着是 CH2Cl2 和 AgBF4 的增加的残留物导致相应钯的干净组成方式 complexMes-5in 高产 82% 中。 翻译结果3复制译文编辑译文朗读译文返回顶部 ...
[translate] aTherefore, after removal of the BH3 group with DABCO, the solvent was removed under vacuum followed by the addition of Ag2O and THF. 所以,在BH3小组的撤除以后与DABCO,溶剂被去除了在Ag2O和THF的加法跟随的真空之下。[translate]
硼烷化合物既能表现路易斯酸性,因分子B-H键中的氢带负电荷,又可表现出路易斯碱性.本文系统研究了R·BH 3(R=THF,DMA,NH 3)与酚类物质在常温常压无催化剂条件下的反应,发现R·BH 3(R=THF,DMA)硼烷中与B相连的负电性氢能够全部与酚中与氧相连的正电性氢发生反应,生成含BO 3的硼酸酯和氢气,但NH 3·BH ...
