(a)
Interpretation:
The appropriate curved arrows and reaction products, for the given electrophilic elimination step, are to be drawn.
Concept introduction:
The curved arrow represents the movement of electrons from an electron-rich site to an electron-poor site.
In electrophilic elimination, an electrophile such as a proton is eliminated from a carbocation, generating a stable uncharged molecule. The electrophile is eliminated from a carbon adjacent to the positively charged carbon. A base is necessary to extract the electrophile being eliminated. The base is electron rich and forms a bond with the electrophile. The electrophile-carbon bond pair moves toward the positively charged carbon, forming a second (

- The reaction shown here is an example of the Favorskii reaction, which involves an R¯ leaving group in a nucleophilic addition-elimination reaction. (a) Draw the complete, detailed mechanism for this reaction and explain why R can act as a leaving NaOH H2O group. (b) Suggest how you can synthesize an ester from cyclopropanone using only this reaction.arrow_forwardThe crossed aldol reaction shown here can be carried out using a weak base such as pyridine. (a) Draw the complete, detailed mechanism for this reaction. (b) Explain why a relatively weak base can be used. EtO OEt H EtO OEt H.

- (SYN) Draw the alkyne that, when treated with diazomethane and irradiated with ultraviolet light, will produce the compound shown here. Draw the complete mechanism for that reaction, too.arrow_forwarddraw all of the mechanism for this given acidarrow_forwardTextbook problem: Suggest short series of reactions that would be expected to transform the material on the right into the desired product shown on left.arrow_forward
- (SYN) Show how to carry out each of the following transformations. (a) O (b) ? ? Pharrow_forwardFrom the table below, pick 2 reactions and draw the complete, detailed (curved arrow mechanism) for each. Thank youarrow_forwardThe first step should be proton transfer. As I included in my work and the second step I think should be nucleophilic attack but I don't know how to continue on from there. Please but problem as a list of reactionsarrow_forward
- (SYN) In the reaction shown here, the aromatic ring has just one chemically distinct, aromatic H, so a single electrophilic aromatic substitution will lead to just a single product. With this in mind, supply the missing reagentsneeded to carry out the transformation.arrow_forwardPlease draw detailed mechanism for this reaction to produce corresponding boronic ester (picture as attached). if X group is electron withdrawing group, will the reaction have the higher chance of happening than in case -X group is electron donating group? Please also explain detailed your answer...arrow_forwardPlease draw the complete, detailed mechanism for each of thesearrow_forward
