Reactions of Carbonyl Metal Hydrides with Methylthiirane and Structure of Bis[(η-cyclopentadienyl)-μ-sulfido-sulfidomolybdenum]Reaction of the carbonyl metal hydrides M(η-C5H5)(H)(CO)3 (M = Mo, W), Mn(H)(CO)5, and Fe(H2)(CO)4 with methylthiirane under mild conditions leads to insertion of sulfur into the metal hydrogen bond with formation of the hydrogen sulfido complexes M(η-C5H5)(SH)(CO)3 (M = Mo, W) (1a, b), [Mn(SH)(CO)4]2 (2), and Fe3S2(CO)9 (4), respectively. The molybdenum and tungsten compounds also form the dimeric complexes [M(η-C5H5)S2]2 (M = Mo, W) (6a, b) as well as the dithiolate bridged complex (η-C5H5)Mo[SCH(Me)CH2S]2Mo(η-C5H5) (5). The X-ray structure of anti-6a has been determined.
Notes:
Die Carbonylmetallhydride M(η-C5H5)(H)(CO)3 (M = Mo, W), Mn(H)(CO)5 und Fe(H2)(CO)4 werden mit Methylthiiran unter milden Bedingungen umgesetzt. Dabei entstehen durch Insertion des Schwefelatoms in die Metall-Wasserstoff-Bindung die Hydrogensulfido-Komplexe M(η-C5H5)(SH)(CO)3 (M = Mo, W) (1a, b), [Mn(SH)(CO)4]2 (2) bzw. Fe3S2(CO)9 (4). Die Molybdän- und Wolframverbindungen bilden spontan oder bei höherer Temperatur die zweikernigen Komplexe [M(η-C5H5)S2]2 (M = Mo, W) (6a, b) sowie den Dithiolat-verbrückten Komplex (η-C5H5)Mo[SCH(Me)CH2S]2Mo(η-C5H5) (5). Die Molekülstruktur von anti-6a wurde röntgenographisch bestimmt.
