溴化铁 (II) 催化具有酮或甲基肟取代基的芳基和乙烯基叠氮化物通过形成 N-O 或 NN 键而转化为 2,1-苯并异恶唑、吲唑或吡唑。这种转化可耐受多种不同的官能团,以促进获得一系列苯并异恶唑或吲唑。 Z-甲基肟的不反应性表明,N-杂环的形成是通过酮或肟对活化的平面叠氮化铁络合物的亲核攻击而发生的。

mechanism by our DFT calculations will stimulate wide application of bulk arene chemicals for the synthesis of value-added polyconjugated chain molecules. Various aryl azide derivatives now can be directly converted into valuable polyconjugated enynes, avoiding traditional synthesis including multistep unsaturated precursors, poor selectivity control, and subsequent transition-metal catalyzed cross-coupling

An improved method for the synthesis of 2-aminoquinolines utilizing microwave-assisted synthesis is described. The process involves rapid microwave irradiation of secondary amines and aldehydes to form enamines followed by the addition of 2-azidobenzophenones with subsequent irradiation to produce the 2-aminoquinoline derivatives. Purification of the products is accomplished in a streamlined manner using solid-phase extraction techniques to produce the desired products in high yields and purity, (C) 2002 Elsevier Science Ltd.

Iron(II) bromide catalyzes the transformation of aryl and vinyl azides with ketone or methyl oxime substituents into 2,1-benzisoxazoles, indazoles, or pyrazoles through the formation of an N−O or N−N bond. This transformation tolerates a variety of different functional groups to facilitate access to a range of benzisoxazoles or indazoles. The unreactivity of the Z-methyloxime indicates that N-heterocycle
