第十一章 羧酸衍生物 Carboxylic Acid Derivatives
g Carboxylic acids are just one member of a class of acyl derivatives, RCOY where the acyl group is bonded to an electronegatives substituent .Y that can act as a leaving group in substitution reactions. Numerous acyl derivatives are possible, but we'll be concerned only with four of the more common ones in addition to carboxylic acids themselves acid halides, acid anhydrides, esters, and amides

己 Acid halides:RCoX Acid halides are named by identifying first the acyl group and then the halide. The acyl group names is derived from the carboxylic acid names by replacing the -ic acid e ending with -yl or the -carboxylic acid ending with -carbonyl
