  Various biologically important 1,5-benzodiazepine derivatives were efficiently synthesized in excellent yields using catalytic amounts of NBS (10 mol %). This inexpensive, nontoxic, and readily available catalyst efficiently catalyzes the condensation of several aromatic as well as aliphatic ketones with substituted o-phenylenediamines.

  An environmentally benign and clean biopolymer-based heterogeneous nanocatalyst was prepared and its properties and morphology were characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD). Then, its catalytic activity was investigated in two important organic reactions. In these reactions, efficient and selective syntheses of 1,2-disubstituted benzimidazole and 1,5-benzodiazepine derivatives were carried out using 1,2-diamines and aldehydes or ketones in the presence of a catalytic amount of magnetically recoverable chitosan-supported iron oxide nanoparticles (Fe3O4/chitosan), as a biodegradable nanocomposite, in ethanol at ambient temperature in high yields. The Fe3O4/chitosan nanocatalyst can be recovered easily and reused without any significant loss of the catalytic activity.

  制备了一种环境友好且清洁的生物聚合物基异质纳米催化剂，并通过扫描电子显微镜（SEM）、能量色散X射线光谱（EDX）和X射线衍射（XRD）对其性质和形态进行了表征。随后，研究了其在两种重要有机反应中的催化活性。在这些反应中，使用1,2-二胺和醛或酮在催化量的可磁回收壳聚糖支持铁氧化物纳米颗粒（Fe3O4/壳聚糖）的存在下，在室温下的乙醇中高效且选择性地合成了1,2-取代的苯并咪唑和1,5-苯并二氮杂卓衍生物。Fe3O4/壳聚糖纳米催化剂可以轻松回收并重复使用，且没有显著的催化活性损失。
