Organic chemistry pka reactivity
WitrynaAns: No, ethanol would be unsuitable for carrying out the reaction between propyne and methyllithium. The pKa of ethanol is ~16, and sodium amide is strong enough a base to readily abstract a proton from the solvent ( pKa of NH 3 is ~38); in doing so, it becomes deactivated and is no longer available to react with propyne (pKa ~25). Witryna28 lis 2024 · Hier we’re really walking to blow up our reaction map, because we’re going up talk about a second very important “hub” for synthesis – alkenes. If you haven’t been noticed…. there what a LOT of alkene reactions. Alkenes are a very versatile construction block in bio chemistry, as MYSELF hope this office will make clear. …
