Therefore, reactions involving organometallic reagents, such as Grignard reactions or metal hydride reductions, may have significantly enhanced reaction rates.
12.
Therefore, these reactions represent Green chemistry, providing a safer alternative to the very common Grignard reaction, performed with Mg.
13.
After studying mathematics at Lyon he transferred to chemistry and discovered the synthetic reaction bearing his name ( the Grignard reaction ) in 1900.
14.
The reaction is a Grignard reaction, followed by a H-shift, an enol-keto tautomerisation and an Aldol addition reaction.
15.
For example, the Grignard reaction between phenylmagnesium bromide and carbon dioxide in the form of dry ice gives the conjugate base of benzoic acid.
16.
As a result of this finding, direct oxidation of Grignard reaction product # was attempted and found to be a more efficient route ."
17.
It can also be prepared via a Grignard reaction by reacting phenylmagnesium bromide ( C 6 H 5 MgBr ) with formaldehyde, followed by acidification.
18.
Compared to Grignard reactions, this reaction is very selective towards aldehydes with large tolerance towards a range of functional groups such as ketones, esters, amides and nitriles.
19.
For these two reasons, Grignard reactions often can have a long induction period, followed by a thermal runaway, even causing the reaction solvent to boil-off.
20.
For use as a solvent in things like Grignard reactions when you absolutely do not want any water present .-- BluePlatypus 22 : 55, 6 May 2006 ( UTC)
