  Ligand-Induced Fragmentation of Methylnickel Phenolates Containing a 2-Aldehyde Function: Structure of (3-tert-Butyl-5-methyl-2-oxobenzoyl)tris(trimethylphosphine)nickel

  摘要：

  O-bridging salicylaldehyde derivatives in dimeric methylnickel compounds NiMe(OR)(PMe3) showing equilibria of cis and trans forms (OR = 2-oxobenzaldehyde (1), 3-tert-butyl-5-methyl-2-oxobenzaldehyde (2), 3,5-di-tert-butyl-2-oxobenzaldehyde (3), 2-oxonaphthaldehyde (4)) spontaneously undergo, upon addition of trimethylphosphine, a fragmentation reaction forming 2-oxobenzoyl-C,O chelating ligands in 18-electron mononuclear complexes Ni(OC=O)(PMe3)3 (OC=O = 2-oxobenzoYl (5), 3-tert-butyl-5-methyl-2-oxobenzoyl (6), 3,5-di-tert-butyl-2-oxobenzoYl (7), 2-oxonaphthoyl (8)). The molecular structure of 6 contains pentacoordinate nickel with a chelate bite angle C-Ni-O = 85.5(1)-degrees. Dissociation of phosphine ligands in 5 gives Ni(OC=O)(PMe3)2 (9) and [Ni(OC)(PMe3)]2 (10), but no mobilization of carbonyl ligands could be observed in the presence of Ni(PMe3)4 as CO acceptor.
