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-butylthiophenyl)thiophene, which shows a potentially...

A series of dendritic cations 1-4 containing Ru2S3 or Rh2S3 units, either in the core or in the dendrons, has been synthesized and characterized. The X-ray crystal structure analysis of 2-Cl shows a trigonal bipyramidal Rh2S3 core with propeller-like para-hydroxyphenyl substituents at the sulfur atoms. Reaction...
