2. Carbenes undergo cyclopropanation reactions with alkenes. It is known that the carbene approaches the alkene in a non-linear rather than a linear fashion. Provide a depiction of the relevant HOMO and LUMO orbital interactions that explain this preference for the non-linear trajectory. Linear H H H H VS. H-C. Non-Linear (Favored) H₂ H H H
1. Consider the Diels-Alder cycloaddition reaction below. D heat H D = deuterium = 2H Draw the major regioisomer (or in other words, constitutional isomer) expected to form. Draw appropriate resonance structures and explain why only one constitutional isomer is expected to form. Discuss if this can be drawn with both groups on the dieneophile being endo or one has to be endo and the other has to be exo.
This is a Diels-Alder reaction between ethylene and cis-1,3-butadiene. For each cycloaddition product, draw in all hydrogen atoms, and write the molecular formula below.
