A novel series of tripodal ligands with thiophenylether arms connected to an anchoring nitrogen has been investigated. Seven tripodal ligands were synthesized by combining methyl, isopropyl, and tert-butyl residue bearing thiophenylether sites as groups w

The factors governing the competition between 1,2- and 1,3-eliminations have been studied and the results obtained have been applied to a biomimetic synthesis of chrysantemol.

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.
