another proton to C2. It was expected that solvent protons would contribute to forming the product from the enediol intermediate of the proton-transfer...

exceptionally basic bis(dimethylamino)carbene R2N−C̈−NR2. It is generated by protonation of (CH3)3COCH(N(CH3)2)2 (Bredereck's reagent). (CH3)3COCH(N(CH3)2)2 +...

Also, the rapid rise of Pacific Rim marques such as Hyundai, Kia, and Proton in the 1990s began to take over the budget sector of the market, in which...

atoms, while the protons of a CH2 group of a terminal allene resonate at around 4.5 ppm — somewhat upfield of a typical vinylic proton. Allenes possess...

benzoic acid product, presumably through the generation and immediate protonation of an aryl anion intermediate. The product is isolated upon acidic workup...

the Solar System, which uranium is named after. A neptunium atom has 93 protons and 93 electrons, of which seven are valence electrons. Neptunium metal...

hydroxide. In the first step, the N-hydroxymethylamide is subject to acid protonation. Post water elimination, a mesomerically stabilized cation forms. This...

exhibited by cyanamide involves additions of compounds containing an acidic proton. Water, hydrogen sulfide, and hydrogen selenide react with cyanamide to...

rearrangement is catalyzed by both Brønsted and Lewis acids, via the protonation of, or coordination to the acyl oxygen atom respectively. For example...
