GRAPHICAL ABSTRACT
The disilyl(4-bromo)aniline (Me3Si)2NC6H4Br (A) readily undergoes metal-halogen exchange to give the reactive organolithium derivative (Me3Si)2NC6H4Li (B). Subsequent reactions with various chlorophosphines, R(R′)PCl, or chloro(disilylamino)phosphines, (Me3Si)2NP(R)Cl, were used to prepare three varieties of the title compounds: (Me3Si)2NC6H4P(R′)R (1: R = R′ = NMe2; 2: R = R′ = OCH2CF3; 3: R = Ph, R′ = OCH2CF3; 4: R = R′ = Ph; 5: R = Ph, R′ = Me), (Me3Si)2NC6H4P(R)N(SiMe3)2 [6: R = Me; 7: R = i-Pr; 8: R = n-Bu, 9: R = OCH2CF3; 10: R = C6H4N(SiMe3)2; 11: R = Ph], and (Me3Si)2NC6H4P(Ph)R [12: R = n-Bu; 13: R = C6H4N(SiMe3)2]. The new compounds 1–13 were generally obtained as colorless, distillable liquids that were fully characterized by NMR (1H, 13C, and 31P) spectroscopy and elemental analysis.
