چکیده
Substantial changes in the chemical shifts of some of the protons in the nuclear magnetic resonance (NMR) spectra of aldehydes and ketones are observed on going from chloro-form or carbon tetrachloride to benzene as solvent. This paper presented a model which correlates the sign and magnitude of these changes with the geometrical relationship between the protons and the carbonyl group.

A mild method for the cross-coupling of arylboronic acids with CF3I via the merger of photoredox (to generate CF3 radical) and Cu catalysis (to generate reactive Cu−aryl species) was developed by Professor Sanford and her co-worker of University of Michigan (J. Am. Chem. Soc. 2012, 134, 9034− 9037). Potassium carbonate was found a base of choice for the promotion of transmetalation in DMF solve...
متن کاملBrønsted acidic ionic liquid as a metal free catalyst for the one-pot synthesis of α-aminonitriles under mild and solvent-free conditions
An efficient, mild and environmentally friendly method was developed for the Strecker reaction to synthesize α-aminonitriles in the presence of methyl imidazolium hydrogen sulfate ([Hmim][HSO4]) as an efficient catalyst. These syntheses were performed via a one-pot three-component condensation of aldehydes (or ketones), amines, and trimethylsilyl cyanide under mild and solvent free c...

MicroEncapsulated Phase Change Materials (MEPCM) are green materials which could be used for thermal energy saving applications in buildings as a non-pollutant method for environmental. PCMs could passively reduce peak cooling loads in hot seasons because of their high energy storage capacities at a constant temperature. Purpose of this paper is manufacturing Microencapsulated PCM (MPCM) pr...
