Abstract
1. The bromination of tert-butyl-3-thienyl sulfide gives the 2-monobromo derivative. 2. tert-Butyl-3-thienyl sulfide is metalated in the 2 and 5 positions of the thiophene ring. The ratio of the 2- and 5-lithium derivatives depends on the reaction conditions. Treatment with excess butyllithium gives tert-butyl-2,5-dilithium-3-thienyl sulfide in good yield. 3. 3-tert-Butylmercapto-2-thiophenecarboxylic acid is decarboxylated quantitatively when refluxed with 10% HCl solution.
