Coordination compounds of some d metals with anthrapyridinedione derivatives: Crystal structure of 2-phenyl-4-(piperidyl-1)-anthra[1,2-b]pyridine-7,12-dionium hexabromodicuprate(II) (HL1)2[Cu2Br6]
摘要:
Complexes of copper(II), nickel(II), and cobalt(II) chlorides and bromides with 2-phenyl-4-(piperidyl-1)-anthra[1,2-b]pyridine-7,12-dione (L-1) and 2-[phenyl-4-(octylamino)-anthra[1,2-b]pyridine-7,12-dione (L-2) were synthesized from neutral and acidic media. The molecular and crystal structure of 2-phenyl-4-(piperidyl-1)-anthra[1,2-b]pyridine-7,12-dionium hexabromodicuprate(II) (HL1)(2)[Cu2Br6] was determined by X-ray diffraction analysis. The spectral characteristics of L-1 and L-2 and their complexes are presented. Formation of their complexes in solutions was studied.
The cyclization of vicinal 1-amino-2-acylvinylated derivatives of aromatic amines
摘要:
A general method for the synthesis of substituted fused polycyclic compounds containing a 4-alkylamino- or 4-dialkylaminopyridine cycle has been proposed. The method includes the addition of primary or secondary amines to vicinal (acylethynyl)arylamines followed by the cyclization of the adducts under acidic or basic catalysis conditions. Various aminonaphthoquinolinediones and aminoquinolines have been prepared in high yields by this method.
