Thermodynamic and spectroscopic properties of 2-pyrrolidinones. 2. Dielectric properties of 2-pyrrolidinone in binary mixtures [PDF]

open access: possibleJournal of Solution Chemistry, 1990
Dielectric permittivities of 2-pyrrolidinone - acetone, -dimethyl sulfoxide,-2-propanol, -dichloromethane and -water systems were measured as a function of mole fraction over the whole composition range at 30 and 50°C. The excess dielectric permittivities are predominantly negative for all the mixtures and the excess molar polarizations are negative ...

Studies on pyrrolidinones. A convenient synthesis of 5‐cyano‐2‐pyrrolidinone derivatives

Journal of Heterocyclic Chemistry, 1986
AbstractThe reaction of 2‐pyrrolidinone‐5‐carboxamide (pyroglutamide) with trimethylchlorosilane and zinc chloride as a catalyst afford in one step a 91% yield of N‐trimethylsilylpyroglutamic acid nitrile whose acylation gives N‐acyl compounds 2b,c.

Unexpected reaction of β-cyclodextrin tosylate with pyrrolidinones

Carbohydrate Research, 2006
Substitution reactions of 6I-O-p-tolylsulfonylcyclomaltoheptaose with alkyl- and arylamines in 1-methyl-2-pyrrolidinone and various pyrrolidinones were investigated. An unexpected reaction of the tosyl group with pyrrolidinones was observed resulting in products deriving from nucleophilic attack by the lactam carbonyl oxygen and further opening of the ...
