  Synthesis and structure of the first monomeric iridium–siloxide complexes

  摘要：

  The first monomeric iridium-siloxide complexes [Ir(cod)(PCy3)(OSiMe3)] (1), [Ir(cod)(PCy3)(OSiMe2CH=CH2)] (2) and [Ir(CO)(PPh3)(2)(OSiMe3)] (3), whose structures have been successfully determined by the X-ray method, have been synthesised and characterised by H-1, C-13, P-31 and Si-29 NMR spectroscopy. In all three complexes the coordination of iridium is square planar. (C) 2002 Elsevier Science B.V. All rights reserved.

• Alkoxy/siloxy group exchange in the system vinyltrialkoxysilane–iridium(<scp>i</scp>) siloxide complex

  A study of reactions of dimeric siloxide iridium complex, [(cod)Ir(μ-OSiMe3)}2] (1) with vinyltriethoxysilane and vinyltrimethoxysilane has revealed a new type of the reaction—alkoxy group transfer from silicon to iridium with a simultaneous transfer of a siloxy group from iridium to silicon—as a result of which vinyldialkoxytrimethyldisiloxane and dimeric alkoxide iridium complex [(cod)Ir(μ-OR)}2] (3) are formed. The structure of [(cod)Ir(μ-OEt)}2] (3a) has been solved by X-ray diffraction.

• Synthesis, structure and catalytic activity of the first iridium(I) siloxide versus chloride complexes with 1,3-mesitylimidazolin-2-ylidene ligand

  The first iridium(I) complex containing siloxyl and N-heterocyclic carbene ligand such as [Ir(cod)(Mes)(OSiMe(3))] (1) and [Ir(CO)(2)(IMes)(OSiMe(3))] (3) have been synthesized and their structures solved by spectroscopy and X-ray methods as well as catalytic properties in selected hydrogenation reactions have been presented in comparison to their chloride analogues, i.e. [Ir(Cl)(cod)(IMes)] (2) and [Ir(Cl)(CO)(2)(IMes)] (4). The attempts at synthesis of iridium(l) complex with tert-butoxyl ligand has failed as leading instead to the iridium hydroxide complex [Ir(cod)(OH)(IMes)] (5) whose X-ray structure has also been solved. All complexes (1)-(5) show square planar geometry typical of the four-coordinated iridium complexes. Catalytic activity of complexes 1 and 2 was tested in transfer hydrogenation of acetophenone and hydrogenation of olefins. (C) 2007 Published by Elsevier B.V.
