Abstract
This invention relates to a process for the selective monochlorination or dichlorination of certain substituted alkenes using trichloroisocyanuric acid. The chlorinated alkenes can be easily hydrolyzed to provide .alpha.-monochloroketones or .alpha.,.alpha.-dichloroketones with a high degree of selectivity. The resulting .alpha.-monochloroketones or .alpha.,.alpha.-dichloroketones have utility as fungicides or function as useful intermediates for fungicides.
