Concept explainers
Interpretation:
Using the number convention for common sequential steps, the following synthetic steps are to be shown:
Concept introduction:
Synthetic steps that are customarily carried out sequentially may be combined using numbers above and below the reaction arrow to distinguish the steps. In a synthetic step, each reaction that is denoted by a number is understood to go to completion before the next reagent is added. Using this convention for sequential steps, reaction conditions can be written after the reagent for each numbered step. The reaction conditions are typically separated from the reactant or reagent by either a comma or a slash.

- Please draw the products obtained in each of the following reactions and circle the major product, thank youarrow_forwardDraw all products of these reactions AND explain which is the major product.arrow_forwardUpon oxidation, phenols are transformed to p-benzoquinone, which can undergo a cycloaddition reaction with a diene to make (1). After acidic workup with HCl, a tautomerization transforms the product back to a phenol derivative (2). Draw the complete, detailed mechanism of p-benzoquinone to (1) and the mechanism from (1) to (2). please explain!arrow_forward
- Predict the product of the reaction between acetic anhydride and each of the following compounds. If no reaction is expected to occur, write “no reaction.” Draw the complete, detailed mechanism for each reaction that does occur.(a) H2O; (b) CH3NH2, pyridine; (c) (S)-butan-2-ol; (d) diethyl etherarrow_forwardPlease explain B, C, and D. Draw the mechanism and the major product(s) of each of the following reaction.arrow_forwardIn the presence of a base which of the following will not form an enolate?arrow_forward
- Select one deactivator & meta director to be on a benzene ring to start. You will then add a bromine to this group showing the COMPLETE mechanism, including all resonance structures. Put a box around the stabilizing resonance structure and explain why it is stabilizingarrow_forwardComplete all the reactions/show the products, and for each reaction clearly and thoroughly explain which mechanism (E1, E2, SN1, SN2) is predominant and how it effects the product formation.arrow_forwardwhat is the minor product of the following reaction.Please draw the mechanismarrow_forward
- Predict/draw the major product of the reaction shown in the picture:arrow_forwardPlease draw the mechanism for the following reaction. The first step in the reaction mechanism is the formation of a carbocation intermediate (shown), followed by a carbocation rearrangement. Which bond moves in the carbocation rearrangement? Which compound shown below has that appropriate bond in pink?arrow_forwardIn a Wittig reaction, a ketone or aldehyde reacts as an electrophile with a nucleophile called a Wittig reagent (or phosphonium ylide) to produce an alkene. The Wittig reagent is commonly synthesized first in a two-step process beginning with an alkyl halide, then reacted with the carbonyl compound. In this problem, you'll explore the mechanism of a multi-step synthesis to make an alkene using the Wittig approach.arrow_forward
