The nano-Al 2O 3-promoted epoxidation of alkenes with molecular oxygen as the oxidant has been developed, providing an efficient route to a variety of epoxides in moderate to excellent yields. The environmentally friendly and efficient nano-Al 2O 3catalyst could be easily recovered and reused five times without significant loss of activity.

The suitability of various acid catalysts for effecting the ring contracting rearrangement of an epoxidized benzyne/furan cycloadduct (1b) to α-formyl-2-indanone (7) was investigated.Nafion-H was demonstrated to be an effective catalyst for this transformation.Competing rearrangement pathways were evident under catalysis by acidic alumina and led to the formation of the novel 1H-2-benzopyran-1-carboxaldehyde (9) in addition to the expected product.
