1-Arylallenes react with singlet oxygen via 1,Zand 1,4\_cycloaddition modes giving rise to three types of carbonyl fragments. l,l-Diphenyl-and 1-methyl-1-phenylallenes react predominantly by the 1,4-mode. Plausible mechanisms are discussed for the formation of the observed products.
Singlet oxygen reactions of 1,3-isoquinolinediones la-le could be sensitized by the anionic sensitizer Rose Bengal (RB) in methanol or by retraphenylporphin (TPP) in the presence of pyridine as a base and a cosolvent in benzene. The products are the corresponding 1,3,4-isoquinolinetriones Za-2e and
