The treatment of [IrCl(cod)]2with (Z)-1-phenyl-2-(4′,4′-dimethyl-2′-oxazolin-2′-yl)-eth-1-en-1-ol (HL) in the presence of base yields the first Ir complex of this ligand class: Ir(κ2-N,O-L)(cod) (3). Complex 3is reactive with MeI or HSnPh3to yield the oxidative addition products 4(trans-Ir(Me)I(κ2-N,O-L)(cod)) and 5(cis-IrH(SnPh3)(κ2-N,O-L)(cod)), respectively. All three of these derivatives have been fully characterised including viasingle crystal X-ray diffraction data. Complex 3is generally resistant to cod ligand substitution but shown to be reactive with CO (g) to give Ir(κ2-N,O-L)(CO)2(6). In addition, 3is demonstrated to be a dehydrogenation catalyst for the conversion of C8H16into cyclooctene and H2under acceptor-free conditions.The synthesis and oxidative addition chemistry of an Ir(I) cod complex (3) containing the enolate derived from (Z)-1-phenyl-2-(4′,4′-dimethyl-2′-oxazolin-2′-yl)-eth-1-en-1-ol is described. Compound 3is shown to be an active alkane dehydrogenation catalyst under acceptor-free conditions. |
