The effect of metal promoter species on the rate of carbonylation of [Ir(CO)2l3Me] was tested. Neutral ruthenium iodocarbonyl complexes such as [Ru(CO)3l2]2> [Ru(CO)4l2] or [Ru(CO)2l2]n were found to give substantial rate enhancements (by factors of 15-20 for a Ru Ir ratio of 1 13 at 93 °C, PhCl). Indium and gallium triiodides and zinc diiodide had comparable promotional effects. By contrast, addition of anionic ruthenium(II) species [Ru(CO)3I3] or [Ru(CO)2I4]2 did not lead to any appreciable promotion or inhibition. This behaviour indicates that the ability to accept an iodide ligand is a key property of the promoter. Indeed, it has been demonstrated that an iodide ligand can be transferred from [ Ir(C0)2l3Me] to neutral ruthenium or indium species [73,74],... [Pg.206]

Gallium triiodide [13450-91 -4], Gal3, is obtained by direct reaction of the elements or by reaction of iodine solution in carbon disulfide on gallium. [Pg.162]

Treatment of cr-bromo ketone with gallium triiodide or methylgallium iodide provides the corresponding gallium enolate, which reacts with carbonyl compounds and imines to give /3-hydroxy ketones and /3-amino ketones, respectively, in moderate yields (Scheme 131).417... [Pg.729]

Similar to aluminum, the synthetic application of metallic gallium or its salts in the aldol reaction produced gallium enolate and its Lewis acidic salt (161). The first example of the gallium enolate aldol reaction was reported by Han and Huang in 1998 (162). The gallium enolates could be formed easily from a-bromoketones and unmodified ketones with gallium triiodide and triethylgal-lium, respectively (163). [Pg.2226]
