Description

General description

1,3-Cycloheptadiene is a 1,3-cycloalkadiene. Isomerization of highly strained (E,E)-1,3-cycloheptadiene was investigated through double bond rotation, and electrocyclic ring closure. [1,5] Sigmatropic hydrogen shifts in 1,3-cyclohepatdiene were studied by density functional calculations.

Application

1,3-Cycloheptadiene was used in the preparation of enantiopure epoxy cycloheptenyl sulfones.
