R 46 Retro-Claisen Cleavage of the beta-Dicarbonyl Ligand in Alcoholysis of Group IVB Metal Chelates [Electronic resource] / Yu. G. Yatluk, S. V. Chernyak, A. L. Suvorov, E. A. Khrustaleva, V. I. Abramova // Russian Journal of General Chemistry. - 2001. - Vol. 71, № 6. - P965-967 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Chelates of titanium, zirconium, and hafnium with -dicarbonyl compounds react with butyl, amyl, and octyl alcohols to give metal alkoxides. The reaction is accompanied by retro-Claisen cleavage of the ligand. The reactivity of the chelates was studied in relation to the ligand structure, nature of the metal, and reaction temperature. The reaction mechanism is discussed \\\\Expert2\\nbo\\Russian Journal of General Chemistry\\2001, V. 71, N 6, p.965.pdf |
