Transition Metal Complexes of Instable Ylides, IV1). Novel Ylidic Chelate Ligands with the Sequence CPNP as Structural Moiety in Tetracarbonylchromium ComplexesThe sulfur ylide complex (CO)5Cr[CH2S(O)Me2] (1) reacts with iminobis(phosphanes) 3a, b to yield five-membered metallacycles 4a, b, in which the novel ylides H2C=PPh2-NR-PPh2 are incorporated as chelate ligands. The reaction of (CO)4Cr[CH2S(O)Me2]2 (5) with (Ph2P)2NH (3d) leads to salt-like 7, which can be protonated and methylated at the nitrogen atom.
Notes:
Der Schwefelylid-Komplex (CO)5Cr[CH2S(O)Me2] (1) reagiert mit den Iminobis(phosphanen) 3a, b zu den fünfgliedrigen Metallacyclen 4a, b, welche die neuartigen Ylide H2C=PPh2-NR-PPh2 als Chelatliganden tragen. Die Umsetzung von (CO)4Cr[CH2S(O)Me2]2 (5) mit (Ph2P)2NH (3d) führt zum salzartigen Komplex 7, der sich am Stickstoffatom protonieren wie auch methylieren läßt.
