Alkali‐Phosphorverbindungen und ihr reaktives Verhalten. XLIX. Thiocarbamoylphosphine

Abstract: Aryl‐ bzw. Alkylisothiocyanate reagieren mit prim. bzw. sek. Phosphinen im Sinne einer Addition zu Bis‐(thiocarbamoyl)‐RP[C(S)NHR′]2 bzw. Thiocarbamoylphosphinen R2PC(S)NHR′ (R = −c‐C6H11, C6H5; R′ = CH3, C2H5, CH2 = CHCH2, C6H5, β‐C10H7, p‐BrC6H4). Die gleichen Verbindungen bilden sich auch aus Alkaliphosphiden MePR2 bzw. Me2PR und Isothiocyanaten R′NCS. Symm. oder unsymm. Biphosphine R2PPR′2 (R, R′ = C6H5, c‐C6H11) verhalten sich gegenüber Phenylisothiocyanat indifferent, nicht hingegen in Äthanol, wob… Show more

“…The ligand diphenylphosphinothioformamide (Ph 2 PC(S)-N(H)Me) is readily prepared from diphenylphosphine and methyl isothiocyanate in equimolecular amounts according to the literature procedure. 14 2) Ω Ϫ1 cm 2 mol Ϫ1 ) rule out an ionic formulation and, furthermore, their IR spectra show, among others, bands at 326 (1) and at 1503, 951 and 791 cm Ϫ1 (2), which are assigned to the Au-Cl 15 and Au-C 6 F 5 16,17 units, respectively. In the 1 H NMR spectra the aminic protons appear at 9.4 (1) and at 8.5 (2) ppm and in their 31 P{ 1 H} NMR spectra a single resonance appears, which is shifted more than 41 ppm downfield compared to that of the ligand, indicative of Au-P coordination.…”
