Synthesis, Structural Characterization and Biological Activity of Novel Cyclohexane-1,3-dione Ligands and Their Metal Complexes.
Some new Zn(II) and Cu(II) complexes [Cu(L1)(OAc)2]∙H2O, [Cu(L1)(NO3)H2O]∙NO3∙3.5H2O, [Zn(L1)(NO3)2]∙4.5H2O, [Zn(L1)(OAc)2(H2O)2]∙3H2O, [Cu2(L2)(OAc)4]∙2H2O∙2DMF, [Cu(L2)2]∙2NO3∙1.5DMF∙H2O, [Zn(L2)2(NO3)2]∙DMF and [Zn2(L2)(OAc)4(H2O)4]∙5H2O; L1 = 2-[2-(2-methoxyphenyl)hydrazono]cyclohexane-1,3-dione and L2 = 2-[2-(3-nitrophenyl)hydrazono]cyclohexane-1,3-dione were synthesized and characterized ...
متن کاملEffect of benzoannulation on tautomeric preferences of 4,6-di(pyridin-2-yl)cyclohexane-1,3-dione
Density functional theory (DFT) calculations at the B3LYP/6-311+G(d,p) level show that 4,6-di(pyridin-2-yl)cyclohexane-1,3-dione is a labile compound. On the other hand, its dienolimine tautomer (4,6-di(pyridin-2-yl)cyclohaxa-1,3-diene-1,3-diol) seems stable enough to be present in vacuum. Alternatively the equilibriated species are (i) dienolimine and enolimine-enaminone ((6Z)-3-hydroxy-6-(pyr...
متن کاملCyclohexane-1,2-dione hydrolase: A new tool to degrade alicyclic compounds
Cyclic alcohols Cyclohexane-1.2-dione hydrolase Thiamine diphosphate Flavoenzyme Alicyclic alcohols are naturally occurring compounds wh ich can be degraded by microorgan isms via cleavage of the ring CC bond. DenitrifyingAzoarcus sp. strain 22Lin grows on cyclohexane-l .2-diol which serves as electron donor and carbon source. The diol is converted to cyclohexane-l.2-dione followed by hydrolysi...
متن کاملA CONVENIENT METHOD FOR PREPARATION AND ISOLATION OF 4-n PROPYL-I ,2,4TRIAZOLINE- 3,5-DIONE
4-n- prophyl- 1,2,4- triazoline-3-5- dione was synthesized from n-propylisocyanate and ethylhydrazine carboxylate in several steps. The title compound was isolated as pink crystals in high yield and purity. This compound was fully characterized by IR and H-NMR spectroscopy
متن کامل5-Chloroindoline-2,3-dione
The title compound, C(8)H(4)ClNO(2), is almost planar (r.m.s. deviation for the non-H atoms = 0.023 Å). In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into C(4) chains propagating in [001] and C-H⋯O inter-actions cross-link the chains.
