Tetrazolverbindungen. 4 [1]. Alkylierung von 1‐Aryl‐5‐(2‐dimethylamino‐vinyl)‐1 H‐tetrazolen

Abstract: Tetrazole Compounds. 4. Alkylation of 1‐Aryl‐5‐(2‐dimethylamino‐vinyl)‐1 H‐tetrazoles Alkylation of 1‐aryl‐5‐(2‐dimethylamino‐vinyl)‐1 H‐tetrazoles 1 with dialkyl sulfates or alkyl iodides yields mainly 4‐alkyl‐1‐aryl‐5‐(2‐dimethylamino‐vinyl)‐1 H‐tetrazolium salts which can be isolated free from isomers by separation as perchlorates 2. The reaction proceeds with retention of the E configuration of the vinyl group. In contrast to 1 the methyl groups of the dimethylamino substituent in 2 are magnetically non‐eq… Show more
