1608-26-0, N,N,N’,N’,N”,N”-Hexamethylphosphinetriamine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of phosphoresorcinarene 2a (0.06 mmol) in0.7 mL of dioxane was added hexamethyltriamidophosphite(0.590 mmol). The reaction mixture was heated for 60 h at 85-95C and then for 40 h at 110-115C. The precipitate was separated by fltration, washed with dioxane, and dried for 4 h at80C/1 mm Hg. White powder; yield 0.066 g (67%); m.p. >360C. 1H NMR (CDCl3, 25C): delta = 0.54 (s, 12H, C(CH3)2),0.75 (s, 12H, C(CH3)2), 2.15 (dd, 2JHH = 10.2 Hz, 3JPH =19.2 Hz, 4H, O-CH2e), 2.21 (s, 6H, C5CH3), 2.22 (s, 6H, C5CH3),2.50 (d, 3JPH = 9.2 Hz, 24H, NCH3), 2.62 (d, 3JPH = 8.4 Hz, 24H,NCH3), 3.24 (dd, 2JHH = 4.1 Hz, 3JPH = 2.3 Hz, 4H, O-CH2a),3.60 (dd, 2JHH = 11.9 Hz, 3JPH = 19.2 Hz, 4H, O-CH2e), 3.89(dd, 2JHH = 8.3 Hz, 3JPH = 2.7 Hz, 4H, O-CH2a), 5.14 (s, 2H,H3h), 6.16 (s, 2H, H3v), 6.33 (s, 4H, H1), 6.59 (d, 3JHH = 6.8 Hz,4H, H2-Naph), 6.74 (dd, 3JHH = 8.2 Hz, 3JHH = 7.3 Hz, 4H, H7-Naph), 6.89 (dd, 3JHH = 8.2 Hz, 3JHH = 6.8 Hz, 4H, H3-Naph),7.00 (dd, 3JHH = 8.2 Hz, 3JHH = 7.3 Hz, 4H, H6-Naph), 7.26 (d,3JHH = 8.2 Hz, 4H, H4-Naph), 7.35 (d, 3JHH = 8.2 Hz, 4H, H8-Naph), 7.38 (d, 3JHH = 8.2 Hz, 4H, H5-Naph). 13C NMR (CDCl3,25C): delta = 11.9 (C5CH3), 12.5 (C5CH3), 20.1 (C(CH3)2), 31.4(s, C(CH3)2), 31.5 (s, C(CH3)2), 36.8 (d, 2JPC = 3.7 Hz, NCH3),36.9 (d, 2JPC = 3.7 Hz, NCH3), 42.5 (C1), 77.5 (O-CH2), 122.6(C5), 123.7 (C5), 124.2 (C6,7,8-Naph), 124.9 (C3-Naph), 126.7(C4-Naph), 127.2 (C2-Naph), 128.2 (C5-Naph), 129.4 (C2), 130.4(C2), 131.5 (C3, C9-Naph), 131.7 (C3), 133.0 (C10-Naph), 137.5(C1-Naph), 147.2 (d, 2JPC = 9.6 Hz, C4OPO), 150.6 (d, 2JPC =7.7 Hz, C4OPN). 31P NMR (CDCl3, 25C): delta = 130.5 (4P),-14.0(4P).
