This page looks at the reaction of aldehydes and ketones with Grignard reagents to produce potentially quite.
Reactions of Alcohols Alcohols are versatile organic compounds since they undergo a wide variety of transformations This is the Williamson Ether synthesis.
GRIGNARD REAGENT REACTIONS Following is the summary chart of applications of Grignard reagent in modern organic synthesis.
Titanium oxide or Zinc powder), two species can be yielded, the Clemmensen Product (diphenylmethane) and the secondary alcohol (diphenylmethanol).
In this special synthesis, the crucial part is the shaking and the amount of catalyst.
Grignard Synthesis of Triphenylmethanol ..
Too much catalyst can give the ultimately reduced product whereas an ample amount will give the secondary alcohol.
Another factor is the concentration of benzophenone.
Alcohol synthesis by 1,2-addition - Organic chemistry
From Wikibooks, but produce the same general results as Grignard reagents, including the synthesis from epoxides.
Grignard Reagents So far, The Grignard reagent therefore provides us with a way of performing the following overall transformation.
GRIGNARD REAGENT | REACTIONS | PREPARATION | …
So far, we have built a small repertoire of reactions that canbe used to convert one functional group to another. We havebriefly discussed converting alkenes to alkanes; alkanes to alkylhalides; alkyl halides to alcohols; alcohols to ethers,aldehydes, or ketones; and aldehydes to carboxylic acids. We havealso shown how carboxylic acids can be converted into esters andamides. We have yet to encounter a reaction, however, thataddresses a basic question: How do we make CC bonds? Oneanswer resulted from the work that Francois Auguste VictorGrignard started as part of his Ph.D. research at the turn of thecentury.
