Description	Tungsten(VI) and molybdenum(VI) complexes [MO(L-1)Cl-2] and [M(X)(L-2)Cl-3] (X = O, NPh) with tridentate aminobis(phenolate) ligand L-1 = methylamino-N,N-bis(2-methylene-4,6-dimethylphenolate) and bidentate aminophenolate ligand L-2 = 2,4-di-tert-butyl-6-((dimethylamino) methyl) phenolate) were prepared and characterised. These complexes are principally stable in open atmosphere under ambient conditions. When activated with Et2AlCl, they exhibited high activity in ring-opening metathesis polymerisation (ROMP) of 2-norbornene (NBE) and its derivatives. Especially complexes [M(NPh)(L-2)Cl-3], which are easily available from corresponding metal oxides MO3 by a simple three-step synthesis, were found very efficient ROMP catalysts for NBE (M = Mo, W) and 2-norbornen-5-yl acetate (M = Mo). Tungsten(VI) and molybdenum(VI) complexes [MO(L-1)Cl-2] and [M(X)(L-2)Cl-3] (X = O, NPh) with tridentate aminobis(phenolate) ligand L-1 = methylamino-N,N-bis(2-methylene-4,6-dimethylphenolate) and bidentate aminophenolate ligand L-2 = 2,4-di-tert-butyl-6-((dimethylamino) methyl) phenolate) were prepared and characterised.

(en) Byly připraveny a charakterizovány wolframové a molybdenové komplexy [MO(L1)Cl2] a [M(X)(L2)Cl3] (M = Mo, W; X = O, NPh) s trojvazným ligandem L1 = methylamino-N,N-bis(2-methylen-4,6-dimethylfenolato) a dvojvazným ligandem L2 = 2,4-di-tert-butyl-6-((dimethylamino)methyl)fenolato). Tyto komplexy jsou za běžných podmínek stálé na vzduchu. Po aktivaci s Et2AlCl vykazují vysokou aktivitu v kruh otevírající metatézní polymerizaci (ROMP) 2-norbornenu (NBE) a jeho derivátů. Zvláště komplexy [M(NPh)(L2)Cl3], které jsou snadno dostupné třístupňovou syntézou z odpovídajících oxidů MO3, jsou velmi účinné ROMP katalyzátory NBE (M = Mo, W) a 2-norbornen-5-yl acetatu (M = Mo).
