摘要:中等活性的单取代芳香化合物与溴在分子筛nay的定量存在下反应,能够以高产率和高选择性反应生成相应的对溴产物.分子筛可以通过加热简单地再生并重复使用.对于甲苯的情况,使用叔丁基次溴酸酯作为试剂,分子筛hx作为催化剂,以及包含四氯甲烷和二乙醚混合物的溶剂,也能达到类似的对位选择性.在光照下,各种分子筛催化乙基4-甲基苯甲酸酯与溴的自由基溴化反应,能提供高产率的乙基4-(溴甲基)苯甲酸酯,但对单溴化的选择性改进不大.

标题:Facile synthesis of 1,9-diacyldipyrromethanes
发明人：LINDSEY JONATHAN S; TAMARU SHUN-ICHI; YU LIANHE
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a method of making a metal complex. The method comprises the steps of: (a) acylating a dipyrromethane or a 1-monoacyldipyrromethane to form a mixed reaction product comprising a 1,9-diacyidipyrromethane; (b) combining the reaction product with a compound of the formula R 2 MX 2 in the presence of a base, where R is alkyl or aryl, M is Sn, Si, Ge, or Pb (preferably Sn), and X is halo, OAc, acac, or OTf, to form a product comprising a metal complex of the formula DMR 2 in the mixed reaction product, wherein D is a 1,9-diacyldipyrromethane; and then (c) separating the metal complex from the mixed reaction product. The method may be utilized for the convenient synthesis and separation of 1,9-diacyldipyrromethanes. Metal complex intermediates useful in such methods are also described.
