Paramagnetic aluminium β-diketiminate.
نویسندگان
چکیده
The β-diketiminate ligand framework is shown to undergo reduction to form a neutral main group radical stabilized by spiroconjugation of the unpaired electron over the group 13 element centre. The synthesized paramagnetic complex was characterized by EPR spectroscopy and computational chemistry.

In the title compound, [Al(C(29)H(41)N(2))(C(2)H(2)N(2)P)(2)], the Al(III) atom is coordinated by four N atoms from β-diketiminate and 1,2,4-diaza-phospho-lide ligands in a slightly distorted tetra-hedral fashion.
متن کاملYttrium-catalysed dehydrocoupling of alanes with amines.
We report [Y{N(SiMe3)2}3] as a precatalyst for the dehydrocoupling of sterically demanding amines with β-diketiminate stabilised aluminium dihydrides. While simple fluorinated anilines readily undergo Al-H/N-H dehydrocoupling under thermal conditions, catalytic methods are required to achieve reasonable rates of reaction for ortho-substituted anilines or hindered aliphatic amines.

The β-diketiminate zinc hydride MesnacnacZnH (1) reacts with CO(2), C(Ni-Pr)(2) and t-BuNCO at ambient temperature with insertion into the Zn-H bond and subsequent formation of the corresponding formato (2), formamido (3) and formamidinato (4) complexes.
متن کاملHydrogen-bond-supported dimeric boron complexes of potentially tetradentate β-diketiminate ligands.
Two dimeric boron complexes of potentially tetradentate and trianionic β-diketiminate ligands bearing phenol substituents were prepared and characterized. The synthetic routes employed were designed to circumvent the undesirable formation of β-ketimines and 2-methylbenzoxazoles observed when traditional synthetic routes toward the target β-diketiminate ligands were attempted. The title complexe...

The phenyl-substituted β-diketiminate ligand precursor (Ph)LH, [(Dipp)NC(Ph)CHC(Ph)NH(Dipp)] (Dipp = 2,6-di-isopropylphenyl) and its lithium and beryllium halide derivatives [(Ph)LLi(OEt2)], [(Ph)LBeCl] and [(Ph)LBeI] have been synthesised and characterised by NMR and X-ray structural analysis. The iodoberyllium complex [(Ph)LBeI] reacts with THF in a well-defined ring-opening insertion reactio...
