full_question: These compounds can be synthesized using Nagata's reagent. Reaction of one of these compounds with tin chloride and hydrochloric acid followed by hydrolysis yields an aldehyde in the Stephen synthesis. These compounds produce chemical shifts of 115-120 ppm in carbon-13 NMR. In another reaction, one of these compounds is nucleophilically attacked by an alcohol in the presence of catalytic hydrochloric acid, forming an intermediate which can be hydrolyzed into an ester or converted into an amidine by adding ammonia. Two equivalents of this functional group are present in the radical initiator AIBN. An alpha-amino one of these compounds can be hydrolyzed to an amino acid in the Strecker synthesis. These compounds can be converted to primary amines via two equivalents of hydrogen and Raney nickel. For 10 points, name these carboxylic acid derivatives produced by the SN2 reaction of an alkyl halide with cyanide, which contain a carbon triple bonded to a nitrogen.
