Complete the reaction scheme below. Show all reagents and intermediates. No reaction is a possible answer. 1) CH3CH2M9B CH3OH H+ (ехcess) но 2) H30*, H2O B A OCH3
The transformation below takes place by two distinct reactions. Intermediate A is formed in the first reaction and then this goes on to the product in the second reaction. Provide a complete curved-arrow mechanism for all steps of both reactions.
2) reaction sequences to carry out those transformations. Draw the expected product of each step proposed. Substantial partial credit can be obtained for incomplete or incorrect answers. You may present your solutions on the following blank page if you need the the following reaction transformations, and propose room. H3C CH, H3C CH3 of HN- -NH HO,C Co,H но H,C CH3 CEN OCH3 OCH3
Please explain the steps clearer. I tried to get help and there were so many other steps. Please help me understand. Thanks
Indicate reagents and conditions needed to impart the transformations below. You do not need to indicate the mechanism, each will require more then one-step.
Nonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.
All rearrangements we have discussed so far have involved generation of an electron-deficient carbon followed by a 1,2-shift of an atom or a group of atoms from an adjacent atom to the electron-deficient carbon. Rearrangements by a 1,2-shift can also occur following the generation of an electron-deficient oxygen. Propose a mechanism for the acid-catalyzed rearrangement of cumene hydroperoxide to phenol and acetone.
The reaction of methylpropene with HBr in ether gives one of the two products below as the major product. Br HBr Br ether Product A Product B Product would have a higher energy transition state for the formation of the intermediate leading to it. O A O B O Both products would have the same transition state.
