A cyclohexanediyl-bridged, bis(N-xylyl) diketiminate ligand, (±)-C6H10(nacnac(Xyl)H)2, LH2 (Xyl = 2,6-dimethylphenyl), was obtained from the reaction of [(2,6-dimethylphenyl)amino]-pent-3-en-2-one first with Meerwein's salt, then with (±)-cyclohexa

Manganese(III) complexes of tetradentate diphenolate-diamino (NNOO(2-)) ligands were prepared from aerobic reaction of MnCl2 with the respective ligands in basic methanolic solution. Methoxide complexes (NNOO)Mn(OMe)(MeOH)0-1 were obtained for three

Condensation of S-methylbenzylamine with 2 equiv. of 2,4-tert-butylphenol yielded the chiral tridentate ligand 2H2, which formed the dimetallic complex (2)(k-N,(μ-O)2ZnEt)((μ-O)2ZnEt), 3, upon reaction with ZnEt2. Reaction of the chiral Schiff base

A new N-heterocyclic carbene ligand N,N'-bis(2-pyridyl)-tetrahydropyrimidinium hexafluorophosphate (1) has been synthesized and characterized. Its homoleptic Ru II complex 2 exhibits a more facile oxidation (+1.17 V vs. SCE) relative to the prototypi

Reaction of β-diketiminate lithium salts, nacnacRLi(THF) (R = 2,6-xylyl (1a), R-CH(Me)Ph (1b)), with ZrCl4 or ZrCl4·THF yielded the mono-diketiminate complexes nacnacRZrCl3(THF), 2a and 2b. Complex 2a did not react further with a second equivalent

Reaction of two equivalents of the lithium salt of N,N′-dibenzyl-2-amino-4-iminopent-2-ene, nacnacBnLi(THF), 1, with CrCl3(THF)3 or CrCl3 yielded nacnacBn2CrCl as a putative intermediate, which could be trapped by addition of 2,6-xylyl isocyanide t

Syntheses of new tetradentate ligands, containing a bianiline backbone and two additional heterocyclic N-donors, and of chiral zirconium complexes containing these ligands as dianions are reported. Crystal structures of some of these complexes show a

Cy(3)PCuMe (1) undergoes reversible ligand redistribution at low temperature in solution to form the tight ion pair [Cu(PCy(3))(2)][CuMe(2)] (3). The structure of 3 was assigned on the basis of (i) the stoichiometry of the 1 = 3 equilibrium, (ii) the

Reaction of a particularly bulky silanol, (2,4,6-Me3C6H2)3SiOH, with Al2Me6 gives, instead of the otherwise preferred unreactive binuclear siloxalanes with two siloxy bridges, a binuclear siloxalane with one siloxy and one methyl bridge, Me2Al(μ-OSi
