Reaktionsschritte

To 2 ml of dimethylformamide, 2.0 g of 2-methylthio-1,3-dithiolium perchlorate was suspended, and 1.1 ml of N-methylaniline was gradually added thereto under stirring at room temperature. The mixture was stirred at room temperature for 1 hour, and then after an addition of 30 ml of ethyl acetate, the precipitated crystals were collected by filtration. The product was recrystallized from acetone, whereby 1.7 g (yield: 69%) of N-(1,3-dithiol-2-ylidene)-N-methyl-N-phenylammonium perchlorate (Compound No. 8) was obtained as crystals having a melting point of 169° C.
