Fecha de publicación: | 17-may-2006 | Editor: | American Chemical Society | Citación: | Organometallics 25(13): 3124-3129 (2006) | Resumen: | In contrast with their stable counterparts bearing the chelating diphosphines, the nickelacyclic O-enolate complexes stabilized by monodentate ligands (R = H, Me, L = PMe3; R = H, L = PMe2Ph ) undergo an unusual self-addition process leading to dinuclear alkoxo-hydroxo derivatives. The α-substituted enolate complexes (R = Me) are less prone to undergo this transformation, and the corresponding nickelacycles with L = PMe3 or PMe2Ph can be isolated in pure form. | Descripción: | 6 páginas, 4 figuras, esquemas. | Versión del editor: | http://dx.doi.org/10.1021/om060183j | URI: | http://hdl.handle.net/10261/37756 | DOI: | 10.1021/om060183j | ISSN: | 0276-7333 |
