Good morning everyone. Today we are going to study about reform and skills reaction. What happened in this reaction? This is also a organometallic based reaction in this reaction. Your Hello ester reacts with an anti-hydro ketone in presence of metallic drink and forms of beta hydroxy ester. Alright. This is when the reaction is somewhat similar to the Grignard reagent. What happens in the Grignard reagent in the Hello Alm? Sorry, at chi-hylide, your heli group is replaced by a colon. So the same thing will be happening here but in this case the starting period have a carburine group present in it. So our first reaction is alpha-helloestern. It reacts with the zinc that is metallurgyne. What happens? The longer of zinc attacks this carbon. This board cleaves and the heli group goes back to the zinc. So this product is formed here. Now the two molecules of this product, same two molecules, diverizes and rearranges the zinc heli. So what happens? This attacks with zinc. This board cleaves. This carbon-eye board attacks here and this board cleaves. So now what is forming here? Two molecules of this compound. Instead of having zinc on this carbon, the product has zinc on the carbon-eye cox. So two molecules will be formed. I will return only one. Now what happens? This reacts with an highly hydro-eropquito. Now this forms a particle form. This carbon-eye cox facilitates this step. In this step your double-horn attacks the carbon-eye carbon and your this board cleaves and form a form with the zinc metal. This oxygen zinc bond cleaves and here are double-born forms. Once again this double-born attacks the carbon-eye carbon. This sink and this double-horn cleaves. The pi-born cleaves and forms a bond between zinc and oxygen. This zinc oxygen bond cleaves and that double-born formation happens here. So ensure what you are getting this product. You will get this product. These two form a six-member cheer-for transition state. This kind of cheer-for-mission informs and this results in the stability of this transition state. So what is happening? It's a transition state here. Now these two reacts and form this product. Now what happens? As it work up, proton from the solvent gets attached to this oxygen and form OH positive. Now halide iron from the solvent attacks the zinc. This bond cleaves and your zinc is eliminated as zinc-lite, Z-Rex2 and this product is formed. In this product you have hydroxychromat of beta position from this carbon icon. So your product is beta hydroxy-ester. So this is the mechanism of your performance reaction. What happens? Your hello-ester reacts with an aldehydrone in the presence of metallic zinc and forms of beta hydroxy-ester. Now if you see the reactants in your products, what is happening? This halide. This halogen is being replaced by your aldehydrone whatever is there. All right? Instead of this X, what is coming here? Your aldehydrone in the form of an hydroxychromat of beta. All right? So this is the performance reaction.
