reportActive / Technical Report | Accession Number: ADA286197 | Open PDF

Abstract:

The synthesis and X-ray structure determination of the novel complex, Cp2TiPh2SiH2PMe3, 4 is reported. The spectroscopic and structural data indicate that 4 is best described as being a hybrid between a titaniumIV silylhydride complex and a titaniumII silane complex. Complex 4 reacts reversibly with N2 to form the bridging dinitrogen complex 5 and, in the presence of norbornene, 4 catalytically dimerizes Ph2SiH2 in quantitative yield. Silane complex, Titanium
