A: Since your question has multiple subparts, we will solve only first three sub parts for you. So when we think about the precursor to this molecule-- so once again, we have an ortho/para director on our ring, and we have a meta director on our ring. Reason is they don't for carbcations readily. Q: Illustrate reaction mechanism for oxidation of CH3 group attached to benzene ring by KMnO4. So for this time, we start out with a bromination reaction to form bromobenzene. Addition of the fourth carboxyl group by way of a cyanohydrin should be straightforward, but a mixture of stereoisomers will result, with the all-cis compound being a minor component.

Orientation in Benzene Rings With More Than One Substituent. Synthesis of substituted benzene rings I (video. This key synthetic intermediate, known as a synthon, may lead to the target molecule in two ways, depending on the order in which conjugate addition and α-alkylation are conducted. In this case it should be apparent that cyclohexanol may be substituted for cyclohexanone, since the latter could then be made by a simple oxidation. Because of their simplicity and broad scope, we shall consider only the first two transforms. Someone correct me if I'm wrong. So our last reaction was a nitration reaction.

Consequently, the logical conception of a multistep synthesis for the construction of a designated compound from a specified starting material becomes one of the most challenging problems that may be posed.
By clicking on the diagram a second time, the reactions which may be used to achieve the proposed constructions will be shown above. B) Note the cis addition. Ortho Para Meta Directors in Electrophilic Aromatic Substitution with Practice Problems. A: Step 1: Birch reduction. So I'm sure you'd get a little bit of ortho as well. Please..... (1 vote). So the immediate precursor to this molecule-- we just take off our nitro group, and we're left with our benzene ring and an acyl group attached to our benzene ring like that. And, actually, it's the exact same groups that we just saw in the previous problem, but this target molecule looks a little bit different. This is a comprehensive problem that covers the following topics and will serve as a review of all of them: Substitution and elimination reactions.
