Please help woth mechanisms and answers for these!
5. Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) 0.15 mmol 1.1 mmol 4. The acetylation of salicylic acid may...

Please use curved arrow notation
Mechanism The synthesis of N-acetylanthranilic acid should proceed all the way to the a benzoxazone product, as shown in the reaction below. Provide the full mechanism for the formation of the benzoxazone compound, via N-acetylanthranilic acid. As you approach the mechanism, consider which functional group is a better nucleophile, the acid or the amine. он 0 NH2

provide a mechanism for this reaction please!
Propose a feasible MECHANISM for the reaction shown below, which is occurring under bask conditions. NEATLY & CLEARLY draw all mechanistic intermediates: use arrows correctly to indicate bond making and bond breaking and clearly indicate which atoms(s), if any bear a charge. Draw only ONE resonance structure for any charged intermediates. Count carbons carefully! NaOCH, CH OH

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.
2) Draw the structure of the enolate formed in the first reaction and then the mechanism of the Aldol reaction in the second reaction. There is an acid work up step at the very end to neutralize charges only. (10 pts) LDA No mechanism Mechanism starts here in this step
