A series of acyclic Schiff bases (1) derived from 1,3,5-triketones and α,ω-alkanediamines has been prepared, and their mononuclear complexes with CuII, NiII, UO2, and VO are described. Phenyl-substituted alicyclic bases are prepared by the reaction of 1-p-X-phenylhexane-1,3,5-trione (X = H, Br, Me, or OMe)(2 mol) and ethane-1,2-diamine (en)(1 mol) in ethanol; the condensation of 7,7-dimethyloctane-2
制备了一系列由1,3,5-三酮和α,ω-烷二胺衍生的无环席夫碱(1),并描述了它们与Cu II,Ni II,UO 2和VO的单核配合物。苯基取代的脂环族碱是通过1- p反应制备的-X-苯基己烷-1,3,5-三酮(X = H,Br,Me或OMe)(2摩尔)和乙烷-1,2-二胺(en)(1摩尔)的乙醇溶液; 7,7-二甲基辛烷-2,4,6-三酮与en的缩合反应类似地产生2,2,7,12,17,17-六甲基-8,11-二氮杂十八烷基-6,12-二烯-3,5, 14,16-四酮(1 I)。6,6-11-Dimethyl-7,10-diazahexadeca-5,11-diene-2,4,13,15-tetraone,(1a)是通过酸水解大环Schiff碱5,9,14,18制备的(1 a) -四甲基-1,4,10,13-四氮杂环-十八烷基-5,8,14,17-四烯-7,16-二酮(2a)。用乙酸金属
