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

TTF-type and TCNQ-type analogues (9-12) have been prepared from a new benzo-fused thiopyranyl precursor 8. The synthetic conditions of 8 were optimized. An anomaly was observed in the 1H NMR spectrum of 9. The crystal structures of 9 and 10 sho

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

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.

Four benzopentathiepins (12, 14, 16, and 18) having a functional group, such as aminoethyl, pyridyl, pyrimidinyl, and thienyl groups, respectively, on the benzene ring were synthesized from 3-substituted 1,2-benzenedithiol by sulfurization with elemental

New 6,7-dimethoxybenzopentathiepin and 6-(2-aminoethyl)benzopentathiepin, which are partial structures of varacin, were synthesized from 1,2-dimethoxybenzene and 1,2-benzenedithiol respectively.

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.

A preparative procedure for the ortho-lithiation of phenylthioethers C6H5SR 1 is described.The preparations of 2-alkylthio-substituted benzoic acids 3, benzophenones 5 and phenylphosphines 6 were carried out in isolated yields of 38-73percent, depending on reaction and substituent.The procedure provides a simple route to dithiocatechol and trithiopyrogallol derivatives 7 and 8.The ring-lithiation step gives the best results for R=t-C4H9 (80-90percent) and R=i-C3H7 (70-80percent).R=C2H5 gave lower yields (ca.45percent), while R=CH3 gave principally lithiation at alkyl carbon.
