Diarylallenylidene Complexes with Pentacarbonylchromium and -tungsten FragmentsThe syntheses of diarylallenylidene complexes with pentacarbonylchromium and -tungsten fragments (OC)5M=C=C=CR2 (M = Cr, W; R2 = 2 C6H5, 2,2'-biphenyldiyl) (1a, b, 2a, b) are reported. The tungstenallenylidene compounds react thermally to give allenylidene-bridged complexes [(OC)5W]2C=C=CR2 (R2 = 2 C6H5, 2,2'-biphenyldiyl) (3a, b). The X-ray structure of the compound [(OC)5W]2C=C=C(C6H5)2 (3a) was determined.
Notes:
Die Synthese von Diarylallenyliden-Komplexen mit Pentacarbonylchrom- und -wolfram-Fragmenten (OC)5M=C=C=CR2 (M = Cr, W; R2 = 2 C6H5, 2,2'-Biphenyldiyl) (1a, b, 2a, b) wird beschrieben. Die Wolframallenyliden-Verbindungen reagieren thermisch zu Allenyliden-verbrückten Komplexen [(OC)5W]2C=C=CR2 (R2 = 2 C6H5, 2,2'-Biphenyldiyl) (3a, b). Die Struktur der Verbindung [(OC)5W]2C=C=C(C6H5)2 (3a) wurde röntgenographisch bestimmt.
