On heating with alkynes, the readily prepared 1,3-dithioles 3 undergo a new cycloaddition reaction and an unprecedented molecular rearrangement with loss of chlorine to give the first 7H-thieno[2,3-c]thiopyran-7-thiones 4 and 4H-thieno[3,2-c]thiopyra

[reaction: see text] In a remarkable cascade reaction, triethylamine is converted into the thienopentathiepin 2a and the heptathiocane 3a by a preequilibrated solution of disulfur dichloride and DABCO in chloroform.

Several of the title compounds Cn are known to be available by cyclisation of the linear precursors with acetone and hydrochloric acid. A two-step synthesis of these linear precursors, Ln, with n = 4–9, and thus potentially of the title compounds,

Trithiazyl chloride 1 converts the oximes of simple cyclic ketones into fused 1,2,5-thiadiazoles and bis-1,2,5-thiadiazoles in mild one-pot reactions. Cyclopentanone oxime gives the bisthiadiazole 3 (20%) in which all four methylene groups have been

Trithiazyl trichloride 1 converts primary and secondary enamines, enamides and 1,2,3-triazoles into 1,2,5-thiadiazoles. These mild reactions provide one-pot routes to various alkyl, aryl, functional and quaternary 1,2,5-thiadiazoles, in moderate to g

N-Ethyldiisopropylamine, S2Cl2 and DABCO in chloroform at room temperature form intermediate salts which react with nucleophiles to give tricyclic bis[1,2]dithiolo[1,4]thiazine derivatives. The reactions of some representative amino compounds as the
