Synthesis of novel alkyl- and aryl sulfides and thiols as precursors for self-assembled monolayers on gold
A series of 4-alkyl-1-bromosulfanylbenzenes having S-methyl 2, S-t-butyl 3, S-trityl 4, S-benzyl S, and S-silylethoxymethyl 6 substituents were prepared and evaluated for their ability to form a monolayer consisting of an S-aryl adsorbate on Au (111) surf
An Iterative Strategy for the Synthesis of Oligothiophenes by Catalytic Cross-Coupling Reactions
An iterative strategy for the synthesis of new sulfur-functionalized oligothiophenes by Suzuki or Stille cross-coupling reactions was applied to the reaction of 4-bromo-tert-butylphenylthioether with thiophene derivatives. The planarity of the oligothiophenes obtained was confirmed by the single-crystal X-ray structure analysis of 2-(4′-tert-butyl-thiophenyl)thiophene, which shows a potentially large electronic conjugation length.
