Synthesis and thermal decomposition of a pyridylene-bridged bis-β-diketiminate magnesium hydride cluster

Synthesis and thermal decomposition of a pyridylene-bridged bis-β-diketiminate magnesium hydride cluster.

Reaction of PYR-(MgnBu)2, in which PYR is 2,6-[(DIPP)NC(Me)CHC(Me)N-]2-pyridine and DIPP is 2,6-iPr2-phenyl, with (DIPP)NH2BH3 gave PYR-[MgNH(DIPP)BH3]2 (56%) which was characterized by crystal structure determination. Addition of THF resulted in β-H elimination and formation of PYR-[MgNH(DIPP)BH3](MgH)·THF (57%), likewise characterized by crystal structure determination. Conversion of the seco...

Reactions of a β-diketiminate zinc hydride complex with heterocumulenes.

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.

New Pyridylene-bridged Bisoxazoles – Synthesis and Structural Study

The bisoxazoles 1a – 1c that feature structures with two oxazole moieties connected to a 2,6pyridylene central linker and contain different aryl substituents in 4and 5-positions of the oxazole rings have been synthesized. Single-crystal X-ray structure determinations of the free ligand 1a, containing the NiCl2 complex of 1c as the CH3COOH solvate as well as the 1,4-dioxane-solvated diester inte...

Crystal structure of a dimeric β-diketiminate magnesium complex

The solid-state structure of a dimeric β-diketiminate magnesium(II) complex is discussed. The compound, di-μ-iodido-bis-[(-{4-amino-1,5-bis-[2,6-bis-(propan-2-yl)phen-yl]pent-3-en-2-yl-idene}aza-nido-κ2N,N')magnesium(II)] toluene sesquisolvate, [Mg2(C29H41N2)2I2]·1.5C7H8, crystallizes as two independent mol-ecules, each with 2/m crystallographic site symmetry, located at Wyckoff sites 2c and 2d...
