review

EWGS- increase dienophile reaction but decrease diene reaction

EDGS- increase diene reaction but decrease dienophile reaction,

the major and minor product of diels alder is the cis (major) and trans

NACN and diene +halogen= addition of CN

sn2:a nucleophilic substitution reaction where a bond is broken and another is formed synchronously

if a diene has an EWG, if it has >1 EDGS it will still be reactive

EWG TO dienophile, EDG to diene

diene must have cis confirmation to overlap p orbitals with trans dienophile

diels alder is concerted pericyclic reaction

if losing H makes you more aromatic, you’re best to be depropronated
