Reported here is the reactivity of mesoionic 1,3-dithiolium-4-olates towards strained alkynes, leading to thiophene cycloaddition products. In the process, the potential of these dipoles towards orthogonal reaction with azides, allowing efficient double ligation reactions, was discovered. A versatile process to access benzo[c]thiophenes, in an unprecedented divergent fashion, was developed and provides a new entry to unconventional polyaromatic thiophenes.

The transformation of mineral bismuthinite, to Bi2S3 nanoparticles, via a simple two-step process is described. The reaction of bismuthinite with two aryldithoic acids gave the complexes; [Bi(S2C(C6H4

In an extension of promising inhibitory results in vitro against Histoplasma capsulatum, correlated earlier using substituent constants developed by regression analysis with 77 disulfides, one symmetrical and 14 unsymmetrical disulfides were prepared (3-17). About half were active in vitro against H. capsulatum (and one against Candida albicans). Groups that seemed most to lead to promising inhibition among the unsymmetrical disulfides were o-HO2CC6H4, (CH2)SO2Na, Me2NCCS), p-ClC6H4, and perhaps p-CH3C6H4; the first two also might be used to increase solubility. Earlier inhibitory promise of the morpholino group did not materialize. None of the group 3-17 was significantly active in vivo. The unsymmetrical disulfides were prepared by reaction of thiols with sulfenyl chlorides or with acyclic or cyclic thiosulfonates. Two six-membered heterocyclic disulfides (5 and 6) were prepared by a novel cyclization, in which carbon disulfide reacted with an (N-alkylamino)ethyl Bunte salt, followed by ring closure; an explanation is suggested for formation of a thiazoline when the N-alkyl group is absent. One of the disulfides disproportionated with astonishing ease (31; 0.3-1 h at 25°C).
