(CH3)2Culi + CH3Cu Ph CI Ph CH3 The ketone intermediate formed in the reaction of an acid chloride with a Grignard reagent cannot be isolated because it reacts too rapidly with the second equivalent of Grignard reagent. To produce a ketone from an acid chloride, one can treat the acid chloride with a lithium dialkylcopper reagent. The reaction occurs by nucleophilic acyl substitution on the acid chloride by the dialkylcopper anion to yield an acyl...

OH H+ CH3 H3C OH Esters can be synthesized by an acid-catalyzed nucleophilic acyl substitution between an alcohol and a carboxylic acid; this process is called the Fischer esterification reaction. Because the alcohol oxygen is a poor nucleophile, the carbonyl carbon is made a better electrophile by protonation of the carbonyl oxygen. The steps of the synthesis are all reversible. The reaction is generally driven to completion by using an excess of the liquid alcohol as a solvent, or by...

Draw the different geometric isomers for dibenzalacetone (there are
3 of them). Why is the trans isomer formed in this experiment?
The purpose of this experiment is to svnthesize dibenzalacetone (trans, trans-1. 5-diphenvl-1.4 pentadien-3-one) through the Aldol condensation of acetone with benzaldehyde. The synthesis begins bv using a strong base to generate the acetone enolate ion. Water (not shown) is formed as a byproduct. The equilibrium position of this reaction strongly favors the starting acetone, and the amount of acetone...
