- Abstract
Photochemistry of Cyclic Acetals of the 1,3-Dioxa-4,6-cycloheptadiene Type UV.-irradiation (λ=254 nm) of 3 gives the isomers ( E)- 5 (4%), ( Z)- 5 (60%) and 6 (3%). On triplet sensitization (acetone; λ ≥ 280 nm) 3 is converted to ( E)- 5 (3%), ( Z)- 5 (7%) and 7 (9%). − The 1π,π*-excitation (λ=254 nm) of 4 yields the isomers 2 (9%), 8 (10%), 9 (34%), 10 (20%) and 11 (3%). On thermolysis (200°) 4 gives 10 (87%) by a Claisen-rearrangement.
