Description / Table of Contents:
(1.4-Dimethyltetrazolium)carbonylferrates, Starting Products for (1.4-Dimethyltetrazolinylidene)- and Bis(methylamino)carbene ComplexesSodium hydrogen(tetracarbonyl)ferrate (4) reacts with 1.4-dimethyltetrazolium tetrafluoroborate (5) to yield a mixture of 1.4-dimethyltetrazolium carbonylferrates (6). These split off hydrogen and nitrogen under formation of (1.4-dimethyltetrazolinylidene)- (7) and [bis-(methylamino)carbene]tetracarbonyliron(0) (8). Structures and bonding properties of these new complexes are discussed by means of spectroscopic data, comparisons are made with (1.3-dimethylimidazolinylidene)tetracarbonyliron(0) (10) and N.N' -dimethylurea (9). The mechanisms of formation of 7 and 8 are discussed.
Notes:
Natrium-hydrogentetracarbonylferrat (4) reagiert mit 1.4-Dimethyl-tetrazolium-tetrafluoroborat (5) zu einem Gemisch von (1.4-Dimethyl-tetrazolium)-carbonylferraten (6). Diese spalten Wasserstoff und Stickstoff ab, wobei (1.4-Dimethyl-tetrazolinyliden)- (7) und [Bis-(methylamino)carben]-tetracarbonyl-eisen(0) (8) entstehen. Struktur und Bindungsverhältnisse dieser neuen Komplexe werden anhand spektroskopischer Daten diskutiert, Vergleiche mit (1.3-Dimethyl-imidazolinyliden)-tetracarbonyl-eisen(0) (10) und N.N' -Dimethyl-harnstoff (9) werden angestellt. Die Bildungsmechanismen von 7 und 8 werden diskutiert.
