Cubane and dicubane complexes stabilised by sterically demanding m-terphenyl ligands.
نویسندگان
چکیده
The reaction between sterically demanding m-terphenyl lithiate complexes and cadmium dihalides yields unusual cubanes where changes in ligand bulk afford different formulations, in particular a rare heterodicubane structure.

Cobalt(II) diaryl complexes react with CO to afford Co(2)(CO)(8) and sterically encumbered ketones whose structure varies depending on the nature of the aryl ligands.
متن کاملExtremely bulky amide ligands in main group chemistry.
The search for extremely sterically demanding monodentate amide ligands to access main group complexes in low-coordination numbers and highly reactive bonding modes is an area of intense research interest. The recent development of three classes of sterically demanding, monodentate amide ligands - the m-terphenyl anilides [N(R){C6H3Ar2-2,6}](-) (Ar = aryl, R = H, methyl, silyl), substituted car...
متن کاملBulky aryl functionalized carbazolyl ligands: amido alternatives to the 2,6-diarylphenyl ligand class?
Sterically encumbered amido ligands based on a 1,8-diarylcarbazol-9-yl backbone have been investigated as electronically distinct alternatives to the widely-used terphenyl ligand class in the stabilization of low-coordinate metal complexes, and structurally characterized for the first time. While 1,8-diphenylcarbazol-9-yl derivatives are readily available, facile rotation about the Cipso-Cipso ...
متن کاملCatalytic reduction of dinitrogen to ammonia at a single molybdenum center.
Since our discovery of the catalytic reduction of dinitrogen to ammonia at a single molybdenum center, we have embarked on a variety of studies designed to further understand this complex reaction cycle. These include studies of both individual reaction steps and of ligand variations. An important step in the reaction sequence is exchange of ammonia for dinitrogen in neutral molybdenum(III) com...
متن کاملA new coupling reaction for the synthesis of ruthenium half-sandwich complexes with sterically demanding cyclopentadienyl ligands.
The reaction of RuCl(3)(solv.)(n) with tert-butylacetylene in methanol or ethanol leads to the formation of chloro-bridged half-sandwich complexes with sterically demanding cyclopentadienyl ligands, which are of high interest as starting materials for the synthesis of novel Ru catalysts.
