Phenyllithium is an organometallic agent with the empirical formula C 6 H 5 Li. It is most commonly used as a metalating agent in organic syntheses and a substitute for Grignard reagents for introducing phenyl groups in organic syntheses. [ 3 ]
Phenyllithium can also be used to modify the properties of phenylsodium. Ordinarily, phenylsodium reacts violently with diethyl ether, but Georg Wittig showed that by synthesizing PhNa with PhLi in ether, the complex (C 6 H 5 Li)(C 6 H 5 Na) n was formed. The phenylsodium component of the complex reacts before the phenyllithium, making it an ...
Free energy is made up of an enthalpy term and an entropy term. [11] = The standard enthalpy change can be determined by calorimetry or by using the van 't Hoff equation, though the calorimetric method is preferable. When both the standard enthalpy change and acid dissociation constant have been determined, the standard entropy change is easily ...

Alcohol-free, dealcoholized and zero ABV (or less than 0.5 percent ABV) wines are popping up everywhere, often credited to the rise in the sober curious movement. But one question lingers: Are they
In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds.These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation.

The chart of the day. What we're watching. What we're reading. Economic data releases and earnings. The C-suite is usually the one holding all the cards.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
