Mesomeric Kations, I. Synthesis of S-Aryl-thiuronium SaltsS-Aryl-tetramethyl-thiuronium perchlorates (3) are synthesized by reaction of tetramethylthiourea with activated aromatic halogen compounds (2) or with substituted diazonium salts. The reaction of tetramethylchloroformamidinium chloride (4) with thiophenols also gives the compounds 3 in high yields.
Notes:
Zur Synthese von S-Aryl-tetramethylthiuroniumperchloraten (3) läßt sich Tetramethylthioharnstoff mit aktivierten Halogenbenzolen (2) oder mit Diazoniumsalzen arylieren. Außerdem führt die Umsetzung von Tetramethyl-chlorformamidiniumchlorid (4) mit Thiophenolen ebenfalls glatt zu den Verbindungen 3.
