Synthese und Strukturen von Imidotitanverbindungen — Steuerung der Bildung monomerer und dimerer Spezies durch Änderung der Basizität des Lösungsmittels

Synthesis and Structures of Imidotitanium Compounds — Directing the Monomer‐Dimer Formation by Changing the Basicity of the Solvents The reaction of (i‐Pr)2PN(SiMe3)2 (1) with elemental sulfur leads to (i‐Pr)2P(S)N(SiMe3)2 (2). Compound 2 reacts with TiCl4 with elimination of chlorotrimethylsilane to yield the adducts [(i‐Pr)2P(S)NTiCl2‐MeCN]2 (3) and (i‐Pr)2P(S)N = TiCl2.3py (4), crystallized from MeCN or pyridine, respectively. Compound 3 crystallises in the space group Pbca, 4 in the space group p&1macr;.
