✦ Synopsis

Ultraviolet irradiation of alloocimene (II) is known to give a-pyronene (Ij2 and a 1,2,4-triene (III).3 The concomitant formation of another photoisomer (IV) is now reported.4 This product,* b.p. 61°/37 mm., was isolated by distillation in 14% yield,after irradiation (A> 250 mu) of a 5% hexane solution of
