WebAnswer (1 of 10): Chichibabin Reaction! Okay, I have two reasons for this answer: First, being the name! —Chee-Chee-Baaa-Been— (Sounds amusing) Second, (Which is nowhere mentioned on the whole internet database on Earth) The final major product obtained has a pyridine ring ( sp2 hybridisation ... WebChichibabin reaction is a method for producing 2-aminopyridine by the reaction of pyridine with sodium amide. The Chichibabin reaction is a nucleophilic substitution on the pyridine ring, the 2nd and 6th positions are therefore favoured over the other positions.
