WebFeb 22, 2013 · The structure of 2 was established using NMR spectroscopy. Thus, the PMR spectrum of 2 exhibited a singlet for H-14 at δ 5.04 ppm whereas the resonance of H-15 at δ 2.25 ppm that was characteristic of the spectrum of 1 was missing. The 13 C NMR spectrum contained resonances for C-13, C-14, and C-15 at 8 135.1, 79.7, and 126.7 ppm, … WebJul 9, 2010 · Melting points were determined on a Boetius microstage. 13 C NMR (75.5 MHz) and PMR (300 MHz) spectra in CDCl 3 were recorded on a Bruker AM-300 spectrometer with SiMe 4 internal standard. Optical density was measured on a Perkin–Elmer 241 MC polarimeter in a 1-dm tube.

Oxidation of Substituted Pyridines by Dimethyldioxirane: Kinetics …

WebJan 4, 2010 · Dimethyldioxirane generated in situ by the caroate-acetone system has been employed by Jeyaraman and Murray for the epoxidation of arenes to arene oxides 〈84JA2462〉. The yields reported for these reactions range from 5% (naphthalene) to 60% (phenanthrene). Dimethyldioxirane (DMDO), also referred to as Murray's reagent in reference to Robert W. Murray, is a dioxirane derived from acetone and can be considered as a monomer of acetone peroxide. It is a powerful yet selective oxidizing agent which finds use in organic synthesis. It is known only in the form of a dilute solution, usually in acetone, and hence the properties of the pure material are largely unknown.
