Cyclobutanolates undergoing one of these reactions can be used to construct seven-member ring frameworks. Quaternary ammonium compounds treated with silver oxide can undergo one of these reactions. A concerted form of these reactions creates anti-periplanar products. Alkyl halides can be transformed with these reactions using DBU and other strong bases. Competition between kinetics and thermodynamics during these reactions can lead to products named for either Hofmann or Zaitsev. The “1cB” form of this reaction occurs when a poor leaving group is present on the alpha carbon in these pi-bond forming reactions. For 10 points, name these general reactions that can form alkenes through either E1 or E2 mechanisms. ■END■
