Hydrolysis of by HCl in THF yields the pentadentate thioetherthiol ligand dpttd-H2 = 2,3,11,12-dibenzo-1,4,7,10,13-pentathiatridecane in the free state.The same principle of synthesis leads also to the hexadentate ligand dhthd-H2 = 2,3,14,15-dibenzo-1,4,7,10,13,16-hexathiahexadecane; ^2- is alkylated by BrC2H4SC2H4SC2H4Br to , which is subsequently hydrolyzed.The reaction of dpttd^2- salts with Mo(CO)6 yields ^2-, where the dpttd ligand functions as tridentate ligand; or yield with pentadentate dpttd.This complex with PMe3 yields .The reaction of the potentially hexadentate dhthd-H2 with Mo^II-carbonyl complexes yields a mixture of and .Furthermore, , which contains totally chlorinated benzene rings as well as the methylhydrazine complex , were obtained as new derivatives of .
