Jung, Jae C.,Watkins, E Blake,Avery, Mitchell A.
, p. 3767 - 3777 (2002)
Concise and efficient methods for the preparation of 3-substituted 4-ethoxycarbonylpyrazolin-5-ones are described. The synthetic strategies involve carbon-acylation in the presence of base, followed by ring cyclization with hydrazine or hydrazine monohydrochloride.
Pd-catalyzed carbonylation for the construction of tertiary and quaternary carbon centers with sp3 carbon partners
Lu, Wei,Li, Yang,Wang, Chao,Xue, Dong,Chen, Jian-Gang,Xiao, Jianliang
supporting information, p. 5243 - 5249 (2014/07/08)
The first examples of a Pd-catalyzed carbonylation of aryl boronic acids with sp3 carbon partners are presented. Various boronic acids were shown to react with 1,3-diesters and 1,3-diketones to afford structurally unique carbonyl compounds. By
TRANSMISSION OF SUBSTITUENT EFFECTS IN PARA SUBSTITUTED BENZOYLMALONATE DERIVATIVES
Bankowska, Zofia,Zadrozna, Irmina,Bochenska, Joanna
, p. 461 - 467 (2007/10/02)
Acidity constants and enol contents of ethyl benzoylmalonate and its para derivatives (CH3O, CH3, Cl, CN, NO2) were determined in 75 vol.percent ethanol-water solutions.Acidity constants of keto and enol forms were calculated and correlated with substituents constants ?p.IR spectra and enol contents were also determined in CCl4 solutions.
