Reactions
As an ordinary acid chloride, isobutyryl chloride is the subject of many reported transformations. Dehydrohalogenation of isobutyryl chloride with triethylamine gives 2,2,4,4-tetramethylcyclobutanedione.[3] Treatment of isobutyryl chloride with hydrogen fluoride gives the acid fluoride.[4]
