- In the beginning of this video https://www.youtube.com/watch?v=9Ng6Zv9oLzk, what reason is given on why the dienophile likes the diene?What are regioselectivity and stereospecificity of E2 reactions? Can somebody please explain them to be with examples?can i get help drawing out actual structures including the nucleophilic addition of Cy2NH to parafomaldehyde and its hemiaminal intermidiate and the condensation step when it is displaced by terminal alkyne forming allene, also what is dioxane getting rid of as the solvent, thanks
