A rarely explored oxidative ring contraction of electron-rich 1,2-diazine is described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that is accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives. In addition, a mechanism proceeding via a bicyclic species was proposed on the basis of an isolated reaction intermediate and DFT calculations. (C) 2020 Elsevier Ltd. All rights reserved.

An efficient heterogeneous catalyst (Ni(II)-Vanillin-Schiff base-MCM-41) has been synthesized by immobilization of nickel(II)-vanillin complex on MCM-41 nanostructure and characterized by XRD, TGA, BET, EDS, SEM, ICP-OES, TEM and FT-IR spectroscopy. The catalytic activity and stability of the prepared compound has been studied in some multicomponent reactions with polyhydroquinoline, 1H-indazolo [1,2-b] phthalazine-trione and 2,3-dihydroquinazolin-4(1H)-one derivatives under mild condition reactions. All the reactions were carried out in the presence of water as the solvent and under solvent-free conditions. The simple work up, mild conditions, excellent yield, inexpensive and non-toxic catalyst; makes this protocol both attractive and economically viable. More importantly, this catalyst can be reused several times without any significant loss of its catalytic activity.
