Transition Metal Complexes with Sulfur Ligands, XXXII. Synthesis of the Sterically Demanding New Thiolate-amine Ligands tbu2-ma-H = 2-Mercapto-3,5-di-tbutylaniline and tbu4-bmae-H2=1,2-Bis(2-mercapto-3,5-di-tbutylanilino)ethane as well as of their Iron, Ruthenium and Zinc...

In order to obtain soluble complexes containing sterically protected metal centers the new bi- and tetradentate thiolate amine ligands 2-mercapto-3,5-di-tbutylaniline (=tbu2-ma-H) and 1,2-bis(2-mercapto-3,5-di-tbutylanilino)ethane (=tbu4-bmae-H2) were synthesized. tbu2-ma-H reacts with FeCl2*4H2O and CO to give tbu2-ma)2>, with Zn(ac)2*2H2O tbu2-ma)2> is obtained whose acid hydrolysis and reaction with H2S, respectively, yield pure tbu2-ma-H.The condensation of tbu2-ma-H with glyoxal yields the respective bis-benzthiazolidine, which is reduced by LiAlH4 in the presence of Na to tbu4-bmae-H2. tbu4-bmae-Li2 reacts with , and , respectively, to yield tbu4-bmae)> (L = CO, PMe3, PPh3).The complexes are more soluble in organic solvents than the corresponding unsubstituted bmae complexes, bmae(2-) = 1,2-bis(2-mercaptoanilino)ethane(2-). - Keywords: Bulky Thiolate-amine Ligands, Synthesis, Iron Complexes, Ruthenium Complexes, Zinc Complexes
