| Abstract: | The reaction of 2-(2-aminophenyl)benzothiazole (Habt) with Re(CO)5Br] led to the isolation of the rhenium(I) complex fac-Re(Habt)(CO)3Br] (1). With trans-ReOCl3(PPh3)2], the ligand Habt decomposed to form the oxofree rhenium(V) complex Re(itp)2Cl(PPh3)] (2) (itp = 2-amidophenylthiolate). From the reaction of trans-ReOBr3(PPh3)2] with 2-(2-hydroxyphenyl)benzothiazole (Hhpd) the complex ReVOBr2(hpd)(PPh3)] (3) was obtained. Complexes 1-3 are stable and lipophilic. 1H NMR and infrared assignments, as well as the X-ray crystal structures, of the complexes are reported. |
