Studies of Organometallic Compounds XVIII:

Synthesis and Caracterisation of p-0x0-bis(dicyclopentadienylmethyltitanium IV)

Summary

( C P ~T ~C H , ) ~O is obtained by reacting (Cp2TiC1),0 with methyllithium. IR., NMR. and MS. spectrum are reported. Autocatalytic decomposition of the product is inferred from differential thermal analytic measurements. A l'exception du p-0x0-bis (tribenzyltitane (IV)) [2], les titanoxanes (Cp,TiX),O Ctudiks (Cp=C5H5, X=halogene, CN, NO,, NCS, OCN, N3) [3], n'ont pas de liaisons 0 Ti-C. Des homologues a liaisons Zr-C ou Hf-C sont toutefois connus: d'une part (Cp,ZrR),O, R = phknyle, p-tolyle [4], benzyle [5], methyle [6] et d'autre part (Cp,HfR),O, R = methyle [7].

Nous avons prepare et caractkrise le p-0x0-bis (mkthyltitanoche), (Cp2TiCH3),0. La synthkse est rkalisee par rkaction de (Cp2TiC1),0 avec du mkthyllithium dans l'kther ou le tktrahydrofurane.
