Yavari, Issa,Adib, Mehdi,Hojabri, Leila
, p. 6895 - 6899 (2002)
Protonation of the reactive 1:1 intermediate produced in the reaction between triphenylphosphine and dimethyl acetylenedicarboxylate by 2-aminophenol, 3-aminophenol, 4-aminophenol and 2-amino-3-hydroxypyridine leads to vinyltriphenylphosphonium salts, whi
Microwave-specific acceleration of a retro-Diels-Alder reaction
Dudley, Gregory B.,Frasso, Michael A.,Stiegman, Albert E.
supporting information, p. 11247 - 11250 (2020/10/06)
A high-temperature retro-Diels-Alder reaction is accelerated by microwave (MW) heating to rates higher than expected based on Arrhenius kinetics and the measured temperature of the reaction mixture. Observations are consistent with selective MW heating of the polar reactant relative to other, less polar components of the reaction mixture.
Three-component reaction of triphenylphosphine, dialkyl acetylenedicarboxylates, and heterocyclic rings and the related iminophosphoranes
Anary-Abbasinejad, Mohammad,Hassanabadi, Alireza,Khaksari, Zahra
, p. 204 - 212 (2011/10/31)
Crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reaction of triphenylphosphine, dialkyl acetylenedicarboxylate, and NH acids, such as 2-aminothiazole and 2-aminobenzothiazole. These stabilized phosphoranes undergo a
Effect of imidazolium salts on the catalytic reaction of 1,3-dioxolanes with methyl diazoacetate
Ivanova,Sultanova,Zlotskii
experimental part, p. 106 - 108 (2011/06/18)
Effect of imidazolium salts, [bmim]+Cl-, [bmim] +BF4 -, and [bmim]+PF6 -, on the reaction of 1,3-dioxolanes with methyl diazoacetate in the presence of copper-containing catalysts was studied. The product composition was found to depend on the reaction conditions and the nature and ratio of components of the catalytic system.
