However, treating 2-lithiothiophene with quinoline at 20°C by Giiman's methodf6] leads only to 2-(2-thienyl)quinoline (2) (38%), indicating steric hindrance of 4-addition by the peri-hydrogen atom of the quinoline. In the following reactions of the quinoline system with 2-lithiothiophene derivatives
