2- -1,3-benzodithiole 1,3-benzodithiolium salt

Ammonia and aromatic and aliphatic primary amines react similarly with a double molar amount of a 4,5-diphenyl-1,3-dithiolium or 1,3-benzodithiolium salt. Both amino hydrogens are replaceable by l,3-benzodithiol-2-yl groups, leading to compounds With secondary aliphatic... 

Phenyl-1,3-dithiolium or 1,3-benzodithiolium cations abstract hydride from cycloheptatriene, giving the thermodynamically more stable tropylium salt and 4-phenyl-l,3-dithiole or 1,3-benzodithiole. ...
