Singlet oxygen is known to undergo a 1,4-cycloaddition reaction with dienes analogous to the Diels-Alder reaction\*. A recent communication3 reported that it can also undergo a 1,3dipolar addition reaction with diazomethane, an extremely reactive species. We wish to report

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.

## Abstract The reactions of singlet oxygen with all possible isomers of mono‐ and dimethylnaphthalenes as well as with 1,4,6,7‐tetramethylnaphthalene have been studied. Apart from 2‐methylnaphthalene, which does not react under our reaction conditions, attack on 1,4‐ and in some cases also on 5,8‐
