1. a. Please draw the scheme for epoxidation of alpha methyl styrene with mCPBA. Include arrows and charges. 1. b. Please draw the reaction mechanism for the epoxidation of mCPBA with alpha methyl styrene. Include arrows and charges.
9.58 (*) Enantioselective epoxidation of trans-stilbene using the Jacobsen catalyst results in an optically active epoxide. On the other hand, when the same conditions are utilized with cis-stilbene as the substrate, the product is optically inactive. Explain this observation H HI =N Mn S,S-Mn-salen NaOCI 80% yield optically active (S,S)-Mn(II)-salen

Write a detailed mechanism for the polymerization of styrene in the presence of benzoyl peroxide. The mechanism should include three distinct steps: initiation, propagation, and termination. For propagation, show the first three polystyrene units.
Write a detailed mechanism for oxidation of (-)-Menthol using CrO2 as a catalyst and Periodic Acid as the terminal oxidant. The final product is Menthone. Use chair conformation and arrow pushing mechanisms.
I wonder if I can get help for Hofmann elimination reaction mechanism by starting the reaction with V. reactant. 6. What would be the reactant in the following reaction sequence? Explain the mechanism. i. CH3l ii. Ag O, H2O iii. heat IV
I need some help with part b in the question please (a) Propose a one-step mechanism using curved arrow notation for the formation of styrene oxide from styrene using MCPBA, as shown below. (b) Propose a step-wise mechanism using curved arrow notation for reaction of styrene oxide with (CH_3)_2 CHNH_2 that includes the structure of the expected product. To simplify the mechanism, do not show formation of enantiomers.
