β¦ Synopsis
The 3,4-hydroxyiodination of 1,2-diacyloxycyclohex-2-enes has been reinvestigated: the nature of the source of positive iodine does not appear to have a pronounced effect upon regiocontrol. Using bulkier acyl substituents, the regiocontrol of the process could be vastly improved.

## Abstract The photoreactions of the methylbenzonitriles; 2,3β, 2,4β, 2,6β, 3,4β, and 3,5β benzonitriles; and 2β²β and 4β²β methoxyacetophenones with cyclopentene and ethyl vinyl ether have been investigated. __Meta__ photocycloaddition is the major process for the benzonitriles with cyclopentene, a
