“…17 In our experiments, we decided to conduct the entire operation consisting of: (a) formation of the HAPT, (b) activation of the C-6 amide, and (c) the amination reaction, as a one-pot process without isolation of the individual tris(dialkylamino)phosphines. We chose secondary amines for the current work for two reasons; primary amines could potentially form polymeric products with PCl 3 and reactions of HAPT with primary amines could lead to iminophosphoranes [(R 2 N) 3 P=NR].…”

“…1,8‐diaminonaphthalene (ACROS) was purified by recrystallization from toluene followed by sublimation and converted to 1,8‐diazidonaphthalene through its diazonium salt 43. Tris(amino)phosphanes were prepared through condensation44 or transamination reactions 45. The P 2 precursors for the syntheses of P 2 ‐HMPN(2N 2 ) and P 2 ‐TPPN(2N 2 ) were prepared in a three‐step procedure from the corresponding phosphanes 28.…”

“…freshly distilled prior to use. Compound 1 was prepared as described [4] [16], diethylamino-diphenylphosphane, Ph 2 PNEt 2 [17] and anhydrous trimethylamine N-oxide [18] were prepared following the reported procedures. 1 H, 13 C and 31 P NMR spectra were recorded on JEOL GXS-270, Bruker DPX 300 and JEOL-400 spectrometers in CDCl 3 or CD 2 Cl 2 solutions at 22 ± 1°C with TMS as internal and H 3 PO 4 (80%, aq.)…”
