โœฆ Synopsis

Recent reports mentioned that photochemical reactions of protic solvents with acyclooctene did not give any volatile adduct in the presence of BTX sensitiaers:

We have now found that protonated BeOH as well as other protic solvents actually add to excited cis-cyclooctene by means of aromatic sensitization. -When a 1% PhH solution of k-cyolooctenecarboxylic acid (I) with unfiltered Hg arc for 48 hr under atmosphere of N2, a bicyclic lactone (II), m.p. 140.2-143.5', was 2 obtained in 20% yield an,d characterieed by comparison with the authentic specimen.

Recent publications on the detailed photoohemiatry of 2-oyolopentenone (1) and -herenone (2) have prompted us to reoord preliminary findings on the photochemical behaviours of the next higher homologue, 2-oycloheptenone (I) in various solventa.
