- Provide the complete mechanism using Curved Arrow Formalism for the reaction of 1-chloro-1-methylcyclopentane treated with NaOMe in MeOH. If more than one product is formed, which is the major, minor, and very minor product? Is the reaction SN1, SN2, E1, or E2. I appreciate the help on this question.Provide the mechansim using curved arrows of the reaction of p-t-butyl phenol treated with acetic anhydride in AlCl3. Include resonance stabilized intermediates and if more than one product is formed, label them as major, minor, etc. thank you for the helpOf the two molecules below select which molecule would be predicted to react faster via an E2 elimination. (hint: stereoelectronic arguments can help)
- Nandor performed the following reaction transformation using a chiral auxiliary to promote good enantioselectivity (the preferential formation of one enantiomer over another) in his product. He reacted benzyl bromide with magnesium metal, to form an intermediate, which he reacted directly with the ketone shown below, along with a chiral auxiliary, to form the product In a separate attempt, Nandor forgot the chiral auxiliary, but decided to finish the reaction nonetheless. He purified his product to remove any solvent, starting material and by-products, and prepared a 0.253 M solution of the target alcohol in acetone (MW = 297.44 g/mol, [α] = 114°•mL•g-1dm-1). He filled the polarimetry cell to a height of 40.5 mm. What is the angle of rotation α that he can expect to measure for the sample?(a) Give a mechanism for this reaction, showing how the two products arise as aconsequence of the resonance-stabilized intermediate.(b) The bromination of cyclohexene using NBS gives only one major product, as shown onthe previous page.
