Web916 CHAPTER 19 • THE CHEMISTRY OF ALDEHYDES AND KETONES. CARBONYL-ADDITION REACTIONS Because LiAlH 4 and NaBH 4 are hydride donors, reductions by these and related reagents are generally referred to as hydride reductions. The important mechanistic point about these reac-tions is that they are further examples of nucleophilic … WebThis Organic Chemistry video explains the Tosylation of alcohol reaction using TsCl and also using TsOH. This will also talk about Alkyl Tosylate.

WebCPP WebVideo transcript. Normally ethers are very unreactive, which is what makes them good organic solvents. However, if you react them with strong acids, you get acidic cleavage of the ether. So if we start with our ether over …
WebDraw out the mechanism for the Fischer Esterification that would occur between pentanoic acid and ethanol. Chemically describe the Fischer Esterification reaction. What is the limiting reagent in Fischer Esterification? Determine and draw the products of the following reaction. OH CH3OH TSOH a. WebMechanism: For such a seemingly simple reaction (replacement of OH by OR) there are actually a lot of steps. Protonation of ... The pKa of that species is about -2 , which is roughly equivalent to that of tosic acid. Hence TsOH is in equilibrium with protonated alcohol, as well as protonated carbonyl and protonated water. Hope this helps – James

Addition of a proton (e.g.: p-TsOH, H 2 SO 4) or a Lewis acid leads to a more reactive electrophile. Nucleophilic attack of the alcohol gives a tetrahedral intermediate in which there are two equivalent hydroxyl groups. One of these hydroxyl groups is eliminated after a proton shift (tautomerism) to give ...
