By incorporating 1,2-benzenedithiol as a chelator to construct cobalt dithiolene species, two negatively charged redox-active metal-organic hosts were obtained. By taking advantage of electrostatic interactions, cationic Ru-based photosensitizers were con

As part of a long-term study of dinuclear iron complexes with sulfur-rich coordination spheres and cofacial, sterically variable binding sites for molecules relevant to nitrogenase, the complex (AsPh4)2 [{Fe('apS4')}2] (5) was synthesized and completely characterized ['apS4'4- = 1,3-bis(2,3-dimercaptobenzamido)propane(4-)]. Complex 5 contains two cofacial [FeIII(S2C6H4R) 2]- units linked by [Fe-S-Fe] thiolate bridges and two peripheral propanediamide ligand backbones that are located on opposite sides of the molecular anion and prevent the complete separation of the two [FeS4] cores of 5 if the Fe-S-Fe bridges dissociate. No marked differences were found in the molecular parameters, spectroscopic, magnetic and electrochemical properties of the [Fe2S8] cores in the anion of 5 and the parent complex [{Fe(S2C6H4)2}2-.

The ortho-lithiation of benzene-1,2-dithiol with three equivalents of nBuLi afforded monoas well as di-C-lithiated intermediates. The surprising kinetically controlled formation of di-C-lithiated species offers the opportunity to obtain dimercaptobenzoic and -terephthalic acid derivatives in a onepot synthesis in reasonable yields. Both compounds are versatile building blocks for the synthesis of macrocycles containing arylenedithiol units. Focusing on novel terephthalic acid derivatives, two preparation routes, via amide and via alkyl linkage, respectively, have been elaborated. The reaction sequence (i) sulfur protection using either isopropyl or benzyl groups, (ii) transformation of the carboxylic function into an amide or an alkyl group and (iii) subsequent removal of the protection groups afforded the terephthaldiamidedithiol 6 and the 1,2-bis(2,3-dimercaptophenyl)ethane 11.

As a part of a broader study directed towards helical coordination compounds with benzenedithiolate donors, we have synthesized the bis(benzenedithiol) ligands 1,2-bis(2,3-dimercaptobenzamido)ethane (H4-1) and 1,2-bis(2,3-dimercaptophenyl)ethan

With the aim of examining the role of steric factors in determining the position of metallation, the reaction of n-butyllithium with a series of 1,2-dialkoxy-, 1,2-alkylthio-, 1,4-dialkoxy-, and 2-t-butyl-1-alkoxy-benzenes has been studied in the presence and in the absence of N,N,N',N'-tetramethylethylenediamine (TMEDA).Steric factors are particularly relevant in the case of 2-t-butyl-alkoxybenzenes where the yields of metallation dramatically decrease passing from the methoxy to the isopropoxy derivative, while with the t-butoxy derivative only cleavage of the ether bond occurs.
