Facile formation of a titanium–carbon bond from TiCl4 by HCl elimination: the synthesis and structure of TiCl3[Me3SiNP(Ph)2CHCH2P(Ph)2NSiMe3]†

Abstract

The reaction of TiCl₄ with the bis-phosphinimine Me₃SiN P(Ph)₂CH₂CH₂P(Ph)₂NSiMe₃ 1 proceeds with evolution of HCl and metallation of one CH₂ group to give TiCl₃{Me₃SiNP(Ph)₂CHCH₂P(Ph)₂NSiMe₃} 2. The crystal structure of 2 is solved and shows a comparatively long Ti–C bond.
