1.2.5. Synthesis, crystal structure and catalytic activity of 2-methoxycarbonylethyldichlorotin hydroxide
Abstract: 2-methoxycarbonylethyldichlorotin hydroxide,
CH3OCOCH2CH2SnCl2(OH) ( 1), has been synthesized by hydrolysis
reaction and characterized by elemental analysis, FTIR,
1H NMR spectroscopy, and X-ray single crystal diffraction.
Compound 1 is a centrosymmetric dimmer, and the tin atom
approximates to octahedral geometry via an intramolecular carbonyl-
to-tin coordination and hydroxo-bridging. The compound
display high selectivity and good catalysis activity on the transesterification
reaction of ethyl acetoacetate with an alcohol.
