Preperations of Heterocycles by using of 2,6-Bis[bis(alkylthio)methylene]cyclohexylidenemalononitriles.2,6-Bis[bis(alkylthio)methylene]cyclohexylidenemalonitriles 1 react with alkanethioles to give 1,3-bis(alkylthio)-5-[bis(alkylthio)methylene]-5,6, #7,8-tetrahydro-isoquinoline-4-carbonitriles 2. Treatment of 1 with hydrogen bromide yields 4,6,7,9-tetrakis(alkylthio)-2,3-dihydro-5,8-diaza-phenalenes 3. On the other hand, 1 can be converted with bromine to 6,9-bis(alkylthio)-4,7-dibromo-2,3-dihydro-5,8-diaza-phenalenes 5. However, the reaction of 1 and N-bromosuccinimide afforded 2,6-bis[bis(alkylthio)methylene]-3-bromo-cyclohexylidenemalononitriles 8.
