For 10 points, name this functional group consisting of a carbon triple bonded to a nitrogen.
One Wikipedia page for a synthesis reaction of these compounds says they form from a reaction of a monosubtituted amide with phosphorous pentachloride. Â The shortest Wikipedia page of a synthesis reaction for this functional group says they can be created with the "chemical reaction of aromatic carboxylic acids with ► metal thiocyanates"; that reaction is named for Letts. Â The main page for this functional group links to a namesake type of oil-resistant rubber used in "pneumatic systems" and latex-free gloves. Â Also formed in the Kolbe Synthesis, whatever the hell a "cuprous cyanide" is reacts with an aryl halide to form one of these in the Rosenmund-von-Braun Synthesis.
