Conversion of o-hydroxyaldehydes and ketones into o-hydroxyanilides by monochloramine
Abstract
Rearrangement of the sodium salts of salicylaldehyde, 2-hydroxyacetophenone, and o-vanillin by monochloramine yielded 2-formamidophenol (88%), 2-acetamidophenol (93%), and 2-formamido-6-methoxyphenol (75%), respectively.
