Usage

General Description

3-Ethylphenylboronic acid is a chemical compound that belongs to the class of organoboron compounds. It consists of a phenyl group with an ethyl substituent attached to a boronic acid functional group. 3-ETHYLPHENYLBORONIC ACID is commonly used in organic synthesis as a reagent for the formation of carbon-carbon bonds, particularly in the Suzuki coupling reaction. It is also used as a building block in the production of pharmaceuticals, agrochemicals, and materials for electronic applications. 3-Ethylphenylboronic acid is a valuable tool in the field of organic chemistry, allowing for the efficient and selective formation of complex molecular structures.

Conformational studies by dynamic NMR. 74. Stereomutations of the conformational enantiomers in peri-substituted 1-acylnaphthalenes

Naphthalenes bearing an acyl and a phenyl group in a peri relationship give rise to a pair of enantiomers in the temperature range where the rotations of the acyl group are slow. Such enantiomers were observed by means of low temperature NMR spectra in chiral environments. The barrier to rotation for the acyl substituents, that causes the interconversion of the enantiomers, was demonstrated to be lower than that for the phenyl group. In an appropriately synthesized derivative it was possible to measure the two barriers that were found equal to 10.4 and 15.9 kcal mol-1, respectively. The barriers for the acyl group rotation increase regularly (from 9.5 to 13.2 kcal mol-1) with the increasing dimension of the RCO groups (R = Me, Et, Pr(i), Bu(t)). When a bromine atom replaces the phenyl group, the enantiomerization barrier for the corresponding acyl derivatives increases significantly.
