WebThionyl chloride is an inorganic acid chloride mainly used as a reagent to prepare carboxylic acid chlorides from carboxylic acids. Application. Thionyl chloride may be used in the following processes: To facilitate the synthesis of indenones from 3-hydroxyindanones via dehydroxylation. Webconverted back to the carboxylic acid or carboxylate salt by either acid or base hydrolysis. Using the chart, an amide cannot be directly converted to an acid chloride. First the amide must be hydrolyzed to the carboxylic acid by acid or base, then reacted with thionyl chloride to yield the acid chloride. WebNitriles can be synthesized by a variety of methods, including reaction of a primary amine with a haloalkane (also known as the Gabriel synthesis), dehydration of primary amides, reaction of a cyanide ion with a primary alkyl halide or a primary alkyl sulfonate, or by reaction of a carboxylic acid with a reagent such as thionyl chloride or ... idv china server
