A series of substituted N-arylphthalamic acids 3a-i has been synthesized by the reaction of phthalic anhydride 1 and aryl- or heterocyclic amines 2a-i, in the absence of solvents, in a domestic microwave oven. The formation of nine N-arylphthalamic acids was accomplished in 1-3 min giving excellent yields for compounds 3a-g, but moderate yield of compounds 3h and 3i, respectively. Compounds 3h and 3i are new. Interestingly, N-arylphthalamic acids 3a-i induced hyperlipidemia in Swiss white mice and also increased animals' body weight. (C) 2001 Elsevier Science Ltd.

Complete and Versatile Post‐Synthetic Modification on Iron‐Triazole Spin Crossover Complexes: A Relevant Material Elaboration Method
paper we study the post‐synthetic modification (PSM) reaction on solid spin crossover (SCO) [Fe(NH2trz)3]X2 (X=NO3, OTs, Cl, SO4, BF4) complexes with different substrates. The wide access to a diversity of functionalized complexes with imine, amide and carbamide groups from the same amino parent compound demonstrates the synthetic approach value of this method. The as‐obtained post‐synthetic complexes
在本文中,我们研究了固态自旋交联(SCO)[Fe(NH 2 trz)3 ] X 2(X = NO 3,OTs,Cl,SO 4,BF 4的合成后修饰(PSM)反应)与不同底物的复合物。可以从同一氨基母体化合物广泛获得具有亚胺,酰胺和氨基甲酰胺基团的功能化复合物,这证明了该方法的合成方法价值。通过IR,固体NMR,元素分析和粉末X射线衍射对合成后的复合物进行了研究,并将其与通过直接合成(DS)途径获得的相应化合物进行了比较。此外,在消化通过PSM反应获得的复合物后,通过溶液中的NMR对游离配体进行了表征,这使我们能够间接确认我们希望合成的复合物的形成。该研究表明,尽管在这些材料中的一维配位链之间建立了结构内聚力,但在许多情况下仍可能进行完整的合成后修饰。
