WitrynaWhile catalytic hydrogenation of alkenes is a powerful reaction, it is a bit too powerful. This reaction will reduce all double or triple bonds to single bonds in your molecule! So, you should be very careful when using this method in your synthesis. WitrynaThe reason for the popularity of mCPBA is that unlike many peroxycarboxylic acids needed to be prepared right before the reaction by mixing a carboxylic acid and hydrogen peroxide, it is a quite stable crystalline solid and can be purchased commercially. how well do rv dishwashers work https://luminousandemerald.com

WitrynaSynthesis. Silyl enol ethers are generally prepared by reacting an enolizable carbonyl compound with a silyl electrophile and a base, or just reacting an enolate with a silyl electrophile. Since silyl electrophiles are hard and silicon-oxygen bonds are very strong, the oxygen (of the carbonyl compound or enolate) acts as the nucleophile to form a Si … WitrynaAnd this time, instead of water acting as a nucleophile, water is going to act as a base. It's going to take a proton. So let's look at the product on the left, here. So this lone pair of electrons would take one of these protons, kick these electrons off onto your oxygen like that. So let's go ahead and draw the result of that acid-base reaction.
