The ammonolysis of esters in liquid ammonia [PDF]
, 2013 The rates of ammonolysis of alkyl benzoate and phenylacetate esters in liquid ammonia increase with the acidity of the leaving group alcohol and show relatively large Brønsted βlg values of −1.18 and −1.34, respectively, when plotted against the aqueous ...

Microstructural properties of non-supported microporous ceramic membrane top-layers obtained by the sol-gel process [PDF]
, 1996 Dried and calcined non-supported membrane top-layers of SiO2, SiO2/TiO2, SiO2/ZrO2 (10, 20 and 30 mol% TiO2 and ZrO2, respectively) and SiO2/Al2O3 (10 mol% AlO1.5) were prepared using acid catalyzed hydrolysis and condensation of alkoxides in ethanol ...

ACS Sustainable Chemistry and Engineering, 2018 Strongly basic, stable ionic liquids are rare. We report the synthesis of a series of stable binary alkoxide ionic liquids. The Hammett basicity of these ionic liquids is comparable to or greater than traditional bases such as pyridine and NaOMe.

Double Metal Alkoxides / Heterometallic Alkoxides
, 1995 Heterometallic alkoxides are those alkoxides having two or more different metals linked via bridging alkoxy groups, via oxo-groups or sometimes metal-metal bonding. The large majority of heterometallic alkoxides corresponds to derivatives in which one of the metals is either an alkali or alkaline earth metal.

Chasing an Elusive Alkoxide: Attempts to Synthesize [OC(tBu)(CF3)2]?
CHIMIA, 2006 The synthesis of the alkoxide [OC(tBu)(CF3)2]? by the reaction of tBuM-reagents (M = Li; MgX) with hexafluoroacetone was attempted. This alkoxide was anticipated to be a good building block for novel weakly coordinating anions.

Ring-opening copolymerization (ROCOP): synthesis and properties of polyesters and polycarbonates [PDF]
, 2015 Controlled routes to prepare polyesters and polycarbonates are of interest due to the widespread application of these materials and the opportunities provided to prepare new copolymers. Furthermore, ring-opening copolymerization may enable new poly(ester–
