Metallacyclodisiladiazanes of titanium and zirconium; synthesis, structure and polymerization studies

A series of metallacyclodisiladiazanes has been prepared. Lithiated (SiMe2NH(Bu)2 (1) reacts with TiCl4 2 THF to give (SiMe2N/Bu)2TiCl2 (4). Methylation or fluorination of 4 leads to (SiMe2NfBu)2TiMe2 (8) and (SiMe2N(Bu)2TiF2 (9), respectively. The reaction of ZrCl4 2 THF with lithiated 1 or [SiMe2NH(4-FC6H4)]2 (2) yields (SiMe2NfBu)2ZrCl2 (5) and [Si-Me2N(4-FC6H4)]2ZrCl2 ·THF (7), respectively. The lithiated ligand [SiMe2NH(2,6-iPr2C6H3)]2 (3) reacts with noncoordinated ZrCl4 to give [SiMe2N(2,6-/Pr2C6H3)]2ZrCl2 (6). X-ray structural analysis of 9 showed it to be a fluorine-bridged dimer in the solid state. Compounds 4, 6, 8 and 9 were found to be catalysts for the polymerization of ethylene.
