- Alkyl diazonium salts are unstable even at low temperature. They decompose to form carbocations, which go on to form products of substitution, elimination, and (sometimes) rearrangement. Keeping this in mind, draw a stepwise mechanism that forms all of the following products. NANO2 он + HCI, H2O NH2 онarrow_forwardReaction of 5,5-dimethoxypentan-2-one with methylmagnesium iodide followed by treatment with aqueous acid forms cyclic hemiacetal Y. Draw a stepwise mechanism that illustrates how Y is formed.arrow_forwardElimination, stereochemical aspects. Draw the major product that is obtained when (2R,3R)-2-Bromo-3-phenylbutane is treated with sodium ethoxide and explain the stereochemical outcome of the reaction using Newman projections.arrow_forward
- Reaction of 5,5-dimethoxypentan-2-one with methylmagnesium iodide followed by treatment with aqueous acid forms cyclic hemiacetal Y. Draw a stepwise mechanism that illustrates how Y is formed.arrow_forwardWhen 2,2-dimethylcyclohexanol is treated with acid, 1,2-dimethylcyclohexene and iso- propylidenecyclopentane are the products obtained. Draw a detailed mechanism that explains this result. CH3 H3O+ CH3 CH3 CH3 OH CH3 CH3 2,2-dimethyl- cyclohexanol 1,2-dimethyl- isopropylidene- cyclopentane cyclohexenearrow_forwardGg.144.arrow_forward
- With 2° or 3° alkyl groups bonded to the ether oxygen, the C—O bondis cleaved by an SN1 mechanism involving a carbocation; with methylor 1° R groups, the C—O bond is cleaved by an SN2 mechanism. Define this ?arrow_forwardDraw the products formed when both cis- and trans-but-2-ene are treated with a peroxyacid followed by -OH (in H2O).Explain how these reactions illustrate that anti dihydroxylation is stereospecic.arrow_forwardH3C N- H₂NNH₂ H⭑ CH3 H3C IN CH3 Hydrazine reacts with 2,4-pentanedione to yield 3,5-dimethylpyrazole. Including protonations and deprotonations, the reaction takes 12 steps. Write out the mechanism on a sheet of paper and then draw the structure of the product of step 6. • You do not have to consider stereochemistry. •You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • In an elimination step, include the structure of the leaving group, but draw it in its own sketcher. Separate structures with + signs from the drop-down menu. ? Sn th Previous Nextarrow_forward
