Quantification of the electrophilic reactivities of aldehydes, imines, and enones.
The rates of the epoxidation reactions of aldehydes, of the aziridination reactions of aldimines, and of the cyclopropanation reactions of α,β-unsaturated ketones with aryl-stabilized dimethylsulfonium ylides have been determined photometrically in dimethyl sulfoxide (DMSO). All of these sulfur ylide-mediated cyclization reactions as well as the addition reactions of stabilized carbanions to N-...
متن کاملNucleophilic Reactivities of Schiff Bases
Dedicated to Professor Heinrich Nöth on the occasion of his 85th birthday The nucleophile-specific parameters N and sN, as defined by the linear free energy relationship log k = sN(N +E) (J. Am. Chem. Soc. 2001, 123, 9500 – 9512), were determined for five imines 1a–e by studying the kinetics of their reactions with benzhydrylium ions in dichloromethane solution at 20 ◦C. These parameters allowe...
متن کاملReActivities ©: autism and play
ReActivities© are digital play sequences which encourage the integration of social, emotional and cognitive development in children on the autistic spectrum. Funding from the National Endowment for Science, Technology and the Arts (NESTA), Learning Programme, has enabled a collaborative approach to the development of the ReActivities© software. As a result of working directly with children on t...
متن کاملImmunological cross-reactivities of sulfocephalosporins.
The immunological cross-reaction among sulfocephalosporins (cefsulodin, SFC-I, SFC-II), cephaloridine, sulbenicillin, penicillin G and 7-aminocephalosporanic acid has been investigated. A specific antibody was produced in rabbits against several structurally related haptens. The sensitization was conducted with a hapten-human serum albumin conjugate, which was prepared in an alkaline solution, ...
متن کاملComposition of the Aldehydes of Clostridium Butyricum Plasmalogens. Cyclopropane Aldehydes.
Recent advances in gas-liquid chromatography have permitted the separation and identification of aldehydes derived from plasmalogens, and a number of analyses of aldehydes from animal plasmalogens have been reported (l-3). Bacterial plasmalogens, on the other hand, have only recently been discovered, and no analyses of their fatty aldehydes are available (4-6). Such analyses would be of particu...
