Chemical Reactions. A chemical reaction is a process that leads to the conversion of one type of chemical substances to another. Chemical reactions can be either spontaneous which means requiring no contribution of energy, or non-spontaneous which means typically following the input of some kind of energy, like heat, electricity or light.

Luu, Quang Huynh (2015) Synthesis of benzofused-P-indolequinones from 1,4-naphthoquinone and selective N-debenzylation by Dess-Martin periodinane. Margolis, Aaron (2015) La otra frontera: Exiles, engineering, and state power in the Chiapan borderlands.

The Wittig reaction is a method of forming carbon-carbon double bonds by converting aldehydes and ketones into alkenes. The first step involves the formation of a phosponium salt from the SN2 reaction of an alkyl halide with the nucleophile triphenylphophine, (C6H5)3P. The Phosphonium salt is then deprotonated (losing the proton alpha to the phosphorous) with a strong base, yielding a neutral.

Improvisational Steps to Break Borders: a Dance Essay. Lisa Naugle is Professor and Chair of the Department of Dance at UC Irvine's Claire Trevor School of the Arts.

Martin (87) calculated the resonance of C-12 as d 47.0, closer to the observed value than the other programs but still 20 ppm upfield of observed. Unfortunately, the predictions made in these programs do not realistically approximate the observed carbon shifts in this molecule. Chemical shift simulation programs are usually empirically based, and chemical shift predictions for fused ring.

Dess-Martin oxidation gave the ketone, which was condensed with the phosphine oxide 18 in a Homer reaction, (21)thereby producing optically pure 7, which was then converted to intermediate 10. The construction of the acyl fragment is shown in Scheme 2.3. Realizing that a carboxylic acid coupling to allylic alcohol 13 would be ideal in the metathesis approach, it was envisioned that an.

Dobrot and co-workers (47) reported the synthesis of 2,5-disubstituted-1,3,4-oxadiazoles 79, conveniently prepared by oxidative cyclization of N-acylhydrazones 78 through use of an excess of Dess-Martin periodinane under mild conditions (Scheme 29). Scheme 29. Oxidative cyclization of N-acylhydrazones using Dess-Martin periodinane.
