  重氮化合物的亲核卤化反应，卤代重氮化合物合成的补充原理：实验和理论研究

  摘要：

  首次提出了三种重氮酯，重氮膦酸酯和重氮哌啶基酰胺的亲核卤化新方法，作为我们先前报道的亲电卤化的补充方法。基于高价α-芳基重氮三氟甲磺酸盐1A，2A和3A，相应的卤代重氮化合物是通过卤化四丁基铵或卤化钾的亲核卤化反应生成的。卤代重氮酸酯和卤代重氮膦酸酯的后续分子间环丙烷化反应以及溴化重氮哌啶基酰胺的分子内热–CH插入反应可在两步后以中等至良好的产率获得。DFT计算被呈现为diazoesters得到洞察亲核取代机理与过渡态与中性亲核试剂二甲硫和三乙胺，并用溴溴化- 。

  The present invention provides a novel ethylenically unsaturated compound which is highly sensitive to scanning exposure due to an ultraviolet to near-infrared laser and is cured to give good physical properties; a light sensitive composition providing good developability and high sensitivity and forming a high strength layer; a planographic printing plate material having advantages that good developability, high sensitivity and high strength layer are obtained, particularly a planographic printing plate material requiring no developing machine which are mounted on a printing press without any development, followed by printing and which provides excellent developability on a printing press and printing durability; and a printing process. The ethylenically unsaturated compound has in the molecule a photo-oxidation group and a polymerizable ethylenically unsaturated bond, and has a predetermined solubility in water or an aqueous alkali solution. The planographic printing plate material is characterized in that it comprises a support and provided thereon, a light sensitive layer containing the ethylenically unsaturated compound, a polyhalogen compound as a photopolymerization initiator, a water-soluble polymer binder as a polymer binder and an infrared absorbing agent.

  日期：2013.8.2

  nucleophilic halogenations of diazoesters, diazophosphonates, and diazopiperidinylamides as complementary methods to our previously reported electrophilic halogenations are presented for the first time. On the basis of hypervalent α-aryliodonio diazo triflate salts 1A, 2A, and 3A, the corresponding halodiazo compounds are generated via nucleophilic halogenations with tetrabutylammonium halides or potassium
