Abstract
The electronic spectrum of Cp2TiS5 shows a long-wavelength absorption
at lambda(max) = 492 nm which is assigned to the lowest-energy S-5(2-)
-->Ti-IV ligand-to-metal charge transfer(LMCT) transition. The photoly
sis of the complex in CH2Cl2 leads to the formation of Cp2TiCl2 and el
emental sulfur. II is suggested that LMCT excitation initiates a reduc
tive elimination with the extrusion of S-5 while the reduced titanocen
e is reoxidized by the solvent.
