Metal Complexes with Carbon Sulfides and Selenides as Ligands, VII. Isothiocyanates as Starting Materials for the Synthesis of (η2-Isothiocyanate-C,S)-, (Dithiocarbimato-S,S′)-, and (Dithiocarbamato-S,S′)bis(phosphane)palladium ComplexesThe complexes Pd(PMe3)4, Pd(PMe2Ph)4, Pd(PMePh2)4, and Pd(PiPr3)2 react with SCNR′ (R′ = Me, Ph) to give the (η2-isothiocyanate-C,S)palladium(0) compounds (PR3)2Pd(η2-SCNR′) (1-5). The IR spectra indicate that the isothiocyanate ligands are coordinated via C and S to the metal. The reaction of (PMe2Ph)2Pd(η2-SCNPh) (3) with SCNPh leads to the very stable (dithiocarbimato-S,S′) complex (PMe2Ph)2Pd(S2CNPh) (6). During the insertion of SCNMe into the Pd-H bond of the cation [(PMe3)3PdH]+ the (dithiocarbamato-S,S′) complex [(PMe3)2Pd(S2CNHMe)]+ (isolated as the BPh4 salt 7) is obtained.
Notes:
Die Komplexe Pd(PMe3)4, Pd(PMe2Ph)4, Pd(PMePh2)4 und Pd(PiPr3)2 reagieren mit SCNR′ (R′ = Me, Ph) zu den (η2-Isothiocyanat-C,S)palladium(0)-Verbindungen (PR3)2Pd(η2-SCNR′) (1-5). Die IR-Spektren zeigen an, daß die Isothiocyanat-Liganden über C und S mit dem Metall koordiniert sind. Die Reaktion von (PMe2Ph)2Pd(η2-SCNPh) (3) mit SCNPh führt zu dem sehr stabilen (Dithiocarbimato-S,S′)-Komplex (PMe2Ph)2Pd(S2CNPh) (6). Bei der Insertion von SCNMe in die Pd-H-Bindung des Kations [(PMe3)3PdH]+ wird der (Dithiocarbamato-S,S′)-Komplex [(PMe3)2Pd(S2CNHMe)]+ (isoliert als BPh4-Salz 7) erhalten.
