Neopentyl alcohol can be prepared from the hydroperoxide of diisobutylene. [3] It can also be prepared by the reduction of trimethylacetic acid with lithium aluminium hydride . Neopentyl alcohol was the first described in 1891 by L. Tissier, who prepared it by reduction of a mixture of trimethyl acetic acid and trimethylacetyl chloride with ...
or neopentyl alcohol primary 2,2-Dimethylpropan-1-ol: 113.1 2-pentanol or sec-amyl alcohol or methyl (n) propyl carbinol secondary Pentan-2-ol: 118.8 3-methyl-2-butanol or sec-isoamyl alcohol or methyl isopropyl carbinol secondary 3-Methylbutan-2-ol: 113.6 3-Pentanol secondary Pentan-3-ol: 115.3 2-methyl-2-butanol or tert-amyl alcohol tertiary ...
The preferred IUPAC name is the systematic name 2,2-dimethylpropane, but the substituent numbers are superfluous because it is the only possible “dimethylpropane”. A neopentyl group attached to a generic group R. A neopentyl substituent, often symbolized by "Np", has the structure Me 3 C–CH 2 – for instance neopentyl alcohol (Me 3 CCH 2 OH
The main structure of chemical names according to IUPAC nomenclature. The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book) IUPAC nomenclature of organic chemistry (Blue Book)
For example, CH 3 −CH(OH)−COOH (lactic acid) is named 2-hydroxypropanoic acid with no "1" stated. Some traditional names for common carboxylic acids (such as acetic acid) are in such widespread use that they are retained in IUPAC nomenclature, [7] though systematic names like ethanoic acid are
The mechanism of the Michaelis–Arbuzov reaction. The Michaelis–Arbuzov reaction is initiated with the S N 2 attack of the nucleophilic phosphorus species (1 - A phosphite) with the electrophilic alkyl halide (2) to give a phosphonium salt as an intermediate (3). These intermediates are occasionally stable enough to be isolated, such as for ...
Pentaerythritol was first reported in 1891 by German chemist Bernhard Tollens and his student P. Wigand. [5] It may be prepared via a base-catalyzed multiple-addition reaction between acetaldehyde and 3 equivalents of formaldehyde to give pentaerythrose (CAS: 3818-32-4), followed by a Cannizzaro reaction with a fourth equivalent of formaldehyde to give the final product plus formate ion.
A classic example of NGP is the reaction of a sulfur or nitrogen mustard with a nucleophile, the rate of reaction is much higher for the sulfur mustard and a nucleophile than it would be for a primary or secondary alkyl chloride without a heteroatom. [4] Ph−S−CH 2 −CH 2 −Cl reacts with water 600 times faster than CH 3 −CH 2 −CH 2 ...
