ne-containing 1,5-enynes with 3,5-dibromo-pyridine N-oxide via a noncarbene model was developed, providing a range of synthetically valuable and useful arylacetaldehyde derivatives in moderate to good yields without oxidation of alkynes. Moreover, the corresponding aldehydes can be further transformed into polycyclicaromatichydrocarbons in the presence of a catalytic amount of Lewis acid In(OTf)3
