Procedure

To 20 ml of tetrahydrofuran, 1.0 ml of morpholine was dissolved, and 2.5 g of 2-methylthio-1,3-dithiolium perchlorate was gradually added thereto under stirring at room temperature. The mixture was stirred at room temperature for 1 hour, and then the precipitated crystals were collected by filtration and recrystallized from ethanol, whereby 2.4 g (yield: 83.3%) of 4-(1,3-dithiol-2-ylidene)morpholinium perchlorate (Compound No. 26) was obtained as crystals having a melting point of from 177° to 178° C.
