The process includes the use of a modified base-exchanged niobium catalyst that is particularly useful for the production of cyclopropyl ketones such as cyclopropyl methyl ketone from cyclopropanecarboxylic acid and acetic acid.Joseph Robert Zoeller...
The proposed method allows a simple homologation of ... S. Xue - 《Synfacts》 被引量: 1发表: 2005年 Zinc-mediated conversion of b-keto esters to y-keto esters. Assesses three methods which were used for the formation and fragmentation of 2-carboxycyclopropy alcohols from ketone esters. ...
摘要: A new and efficient procedure for the transformation of α-diazo-β-hydroxy esters into the corresponding β-keto esters, which involves the use of Rh2(OAc)4, is described.关键词: carboxylic acid esters (acyclic compounds DOI: 10.1039/C39790000959 被引量: 27 ...

used a [BMIM][BF4] electrolyte to construct a C–C bond between CO2 and aromatic ketone and synthesized α-hydroxy-carboxylic acid methyl ester [104]. In addition, the results show that temperature, current density, total charge, electrode, and reactant concentration have significant effects on...
This invention provides a method for thermally converting volatile fatty acid (VFA) salts to ketones by mixing dry calcium salts of VFAs with hot heat transfer agent in an evacuated container, thereby causing thermal decomposition of the calcium salts of VFAs to form ketone-containing vapor and ca...
Understanding the reaction mechanism of methanol conversion is essential for the development of high-performance catalysts and optimization of chemical process, but is rather challenging due to the complex reaction network involved in such reaction3,8,9,10. Fig. 1: Roles of aldehyde/ketone in ...
alkyl-sulfides such as methyl sulfide, alkyl-amines such as methyl amine, alkyl-ethers such as dimethyl ether, diethyl ether and methylethyl ether, alkyl-halides such as methyl chloride and ethyl chloride, alkyl ketones such as dimethyl ketone, formaldehydes, and various acids such as acetic acid...

Three major degradation products have been observed, namely 5,8-diethyl-6,7-dodecanedione (diketone), 5,8-diethyl-6,7-dodecanedione monooxime (also known as 5,8-diethyldodecane-6,7-dione hydroxyiminoketone, but for brevity is simply referred to as keto-oxime) and 5,8-diethyl-7-hydroxy...
