Abstract:
Reaction of (1) in CH 2 Cl 2 with benzimidazole yields . The salt [4] + BPh 4 - has been prepared in THF by metathesis of [4] + Cl - with NaBPh 4 . Deprotonation of the cationic ring in [4] + BPh 4 - was accomplished using 1,8-diazabicyclo[5.4.0 1,7 ]undec-7-ene and resulted in the six-membered carbacyclophosphazene (6). Treating 1 with 8 -hydroxyquinoline in CH 2 Cl 2 yields the octahedral cis-complex = 8-oxyquinolinate group). The com pounds [4] + BPh 4 - , 6 and 7 are characterized by their IR, Raman, 31 P{ 1 H} NMR, 13 C{ 1 H} NMR, 1 H NMR and mass spectra. Crystals suitable for X-ray structure analyses have been obtained for [4] + BPh 4 - and 7×0.5 CH 2 Cl 2 . The colourless plates of [4] + BPh 4 - crystallize in the triclinic space group P1̄, with the lattice constants a = 1172.7(3), b = 1326.2(3), c = 1806.1(6) pm; α = 100.79(2), β = 103.71(3), γ = 108.18(2)°. The black blocks of 7×0.5 CH 2 Cl 2 crystallize in the monoclinic space group P 2 1 /c with the lattice constants a = 1159.0(10), b = 2008.9(10), c = 2034.6(12) pm; β = 105.86(5)°.
