摘要:双酸官能化的苯胺phn [(ch 2)3 B(c 6 F 5)2 ] 2在中心碱基功能处显示快速交换的硼酸基团,并且由于两个路易斯酸的协同氢化物结合而成为活性的受阻路易斯对.在这里,我们报告了对中心氮原子上不同取代基的影响以及与磷交换氮的影响的研究.用一当量的hb(c 6 F 5)2处理二烯丙基叔丁基苯胺导致形成一个七元氢硼化亚胺基环;单氢硼化后,在闭环作用下,中间形成的受阻的路易斯对与第二烯丙基胺官能团反应.通过二烯丙基苯基膦和二烯丙基叔丁基膦的氢硼化反应制备了具有两个酸位的磷基路易斯对.与苯胺phn [(ch 2)3 B(c 6 F 5)2 ] 2不同,双氢硼化物种(t Bu / Ph)p [(ch 2)3 B(c 6 F 5)2 ] 2在溶液中未显示出硼路易斯酸官能团的动态交换,并且在h / D加扰和氢化反应方面均没有催化活性.量子化学研究表明,B-p键解离的吉布斯自由能比氮类似物大

标 题:Chiral porphyrins, chiral metalloporphyrins, and methods for synthesis of the same
发明人：ZHANG X PETER; CHEN YING; GAO GUANG-YAO
权利人:UNIV TENNESSEE RES FOUNDATION
摘要:Novel methods of synthesizing heteroatom-containing chiral porphyrins and chiral metalloporphyrins and the novel chiral porphyrins and chiral metalloporphyrins themselves are disclosed. Metal complexes of the chiral porphyrins are prepared in high yields and shown to be active catalysts for highly enantioselective and diastereoselective cyclopropanation, aziridination, and epoxidation of alkenes under a practical one-pot protocol.

摘要:The invention relates to a method of preparing statistical microgels. The inventive method comprises a step involving the radical polymerisation of a composition containing: at least one monoethylenically-unsaturated monomer, at least one multiethylenically-unsaturated monomer, a free radical source and a control agent. The invention also relates to first generation microgels thus prepared and all the compounds resulting from said microgels (next-generation microgels).

权利人:UNIV TENNESSEE RES FOUNDATION
摘要:Novel methods of synthesizing heteroatom-containing porphyrins and metalloporphyrins are disclosed. Novel heteroatom-containing porphyrin and metalloporphyrin compounds are also disclosed. The new methods advantageously utilize metal-catalyzed cross-coupling and amination reactions to produce porphyrin compounds useful in a variety of practical applications.
