Zhu, Hualing published the artcileStructures, spectroscopic analysis, herbicidal activities and enamine-aminone tautomerism of new \u03b2-diketone derivatives modified with glycylglycine methyl ester<\/i><\/b>, Recommanded Product: 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one<\/a>, the publication is Journal of Molecular Structure (2015), 170-177, database is CAplus.<\/p>\n

New \u03b2-diketone derivatives modified with glycylglycine Me ester have been synthesized and characterized by IR, UV, 1<\/sup>H NMR, 13<\/sup>C NMR, Elemental anal. and single-crystal X-ray diffraction, the anal. results show that compound 1 and compound 2a exist in enamine form while compound 2b exists in aminone form. The optimized geometries and theor. vibrational frequencies of the compounds calculated by using DFT\/B3LYP with 6-31g (d, p) basis set in the ground state can well reproduce the exptl. data. The results of herbicidal activity tests indicate that all the tested compounds own higher inhibition ability to monocotyledon than to dicotyledon, especially to green-bristlegrass with the inhibitory rates about 100%. Theor. enamine-aminone tautomerism study at DFT\/B3LYP\/6-31g (d, p) shows that tautomerism between compound 2a and 2b is mainly caused by the proton transfer.<\/p>\n
