Recent Tutoring Session Reviews
"Worked on limiting reactant problem for upcoming quiz. Worked on reflection questions from class project."
"We reviewing chemistry concepts that the student was unfamiliar with, such as thermochemistry and stoichiometry."
"We worked on problem set 3. Problem 2 was a Schlosser modification of the Wittig reaction. We worked on the mechanism on the formation of the ylide which then attacks the carbonyl to form the betine intermediate which normally collapses to give the cis product. But further deprotonation of the betine intermediate and reprotonation from the less hinder sides gives the trans product. Problem 3 was a retrosynthetic problem that gave two different products based on the same starting materials. First, we had to complete a retrosynthesis that gave common starting materials and then choose the correct reagents to for path A allow for Ballis HIllman reaction and for path B enamine addition to unsaturated carbonyl. With problem 4 we were required to do a reaction search to find the desired reaction give in the problem we then had to provide the mechanisms of a Michael addition, followed by an azide reduction using phosphine followed by a Aza-Wittig reaction."
