η-Cyclopentadienylimido molybdenum chemistry: hydrido, alkyl and η-alkyl derivatives
Abstract
The following compounds have been prepared and characterized: [Mo(η-C5H4R)Cl3(NBut)](R = H, Me or Pri), [{MoCl3(µ-Cl)(NBut)}2], cis- and trans-[{Mo(η-C5H4Me)(NBut)(µ-NBut)}2], [{Mo(η-C5H4Me)O(µ-NBut)}2], [Mo(η-C5H4Me)(η-C2H4)Me(NBut)], [Mo(η-C5H5)(η-C2H4)Ph(NBut)], [Mo-(η-C6H4Me)(η-C2H4)(H or D)(NBut)], [Mo(η-C5H4Me)(PMe3)Cl(NBut)], [Mo(η-C5H4Me)(PMe3)-Me(NBut)], [Mo(η-C5H4Me)(PMe3)2(NBut)]+A–(A = Cl or BF4), [Mo(η-C5H4Me)(PMe2Ph)Cl-(NBut)], isomers of [Mo(η-C5H4R)(η-C3H5)(NBut)](R = Me or Pri), and [Mo(η-C5H4Me)(η-C2H4)-(σ-C3H5)(NBut)]. The crystal structure of [{MoCl3(µ-Cl)(NBut)}2] has been determined. These compounds include the first or rare examples of combinations of ligands with the imido group, for example, imido η3-allyl derivatives.
