abstract

  • The anionic, bis(phosphite)iron hydride complex [Et4N] [HFe(CO)2(P(OPh)3)2] reacts with aryl disulfides to yield simple, monofunctional iron thiolate anions, (ArS)Fe(CO)2(P(OPh)3)2- (Ar = Ph, Tol). Methylation of the thiolates resulted in the formation of thioether species (ArSMe)Fe(CO)2(P(OPh)3)2, while protonation resulted in the formation of the stable thiolate-hydride complexes (ArS)Fe(H)(CO)2(P(OPh)3)2. cct-(PhS)Fe(H)(CO)2(P(OPh)3)2 was characterized by X-ray diffraction and found to be a regular octahedral complex in which the phosphite ligands are trans and the carbonyls cis, mutually trans to the hydride and benzenethiolate ligands. The hydride was located 1.41(7) from Fe with H-Fe-S = 89(4). (PhS)Fe(H)(CO)2(P(OPh)3)2 crystallized in the monoclinic space group P21/n with a = 9.935(2) , b = 36.185(5) , c = 12.112(2) , = 113.42(1), V = 3995.5(0) ,3 and Z = 4. (PhS)Fe(H)(CO)2(P(OPh)3)2 was protonated to form the novel thiol-hydride complex (PhSH)Fe(H)(CO)2-(P(OPh)3)2+. 1994, American Chemical Society. All rights reserved.
