摘　　要：本文报道了两种Curtis环镍(Ⅱ)配合物[MIL^1](CIO_4) _(?)[NIL^2](CLO_4)_2催化NaBrO_3氧化芳香有机底物没食子酸或焦性没食子酸而产生的新型振荡化学反应,L^1:Me_(?)[14]-4,11-dieneN_4,L^2:Me_(?)Et_4[14]-4,11-dieneN_4,测出了两种体系振荡反应发生的各物种的初始浓度范围,研究了各物种初始浓度以及自由基抑制剂和还原性物种等对振荡反应的影响。In this paper, we found that in aqueous solutions, [Ni (Me_6 [14]-4, 11 -dieneN_4)]^(2+) and [Ni (Me_2Et_4 [14]-4, 11-dieneN_4)]^(2+), can act as catalysts in the bromate-gallic acid (or pyrogallic acid) -sulfuric acid system. The regions of existence of concentration oscillations for the systens catalyzed by [Ni(Me_6 [14]-4, 11-dieneN_4)]^(2+) and (Ni (Me_2Et_4 [14]^(-4), 11-dieneN _4)]^(2+) have been determined. The concentration oscillations of these systems are damped due to the slow consumption of the catalyst Pyrogallic acid can alsobe servec as organic substrate to produce oscillations.In some espects, the catalyzed oscillations behave similarly to the[NiATH] ^(2+) catalyxed ones.
