You may wish to address the following issues in your response if they are pertinent to the reaction(s) you propose to employ:1) Chemoselectivity (why this functional group and not another?)
2) Regioselectivity (why here and not there?)
3) Stereoselectivity (why this stereoisomer?)
4) Changes in oxidation state.
Please make it in detail and draw it out too in what step what happens. Thank you for helping me!
1) Chemoselectivity (why this functional group and not another?)
2) Regioselectivity (why here and not there?)
3) Stereoselectivity (why this stereoisomer?)
