Isolated yield 1.75 g, 90%. ¹H NMR (400.1 MHz, CD₂Cl₂, 30 °C): δ 7.43-7.34 (m, 4H, ArH), 7.34-7.25 (m, 6H, ArH), 3.59 (s, 1H, cage-CH), 3.50 (m, 1H, cage-CH), 3.10-1.30 (bm, 9H, cage-BH), 2.49 (bm, 2H, PCH₂), 2.29 (m, 2H, SCH₂); ¹³C{¹H} NMR (100.6 MHz, CD₂Cl₂, 30 °C): δ 138.9 (d, ArC, J_C-P= 14 Hz), 133.3 (d, ArC, J_C-P= 18 Hz), 129.2 (s, ArC), 129.1 (d, ArC, J_C-P= 6 Hz), 53.9 (s, cage-CH), 48.6 (s, cage-CH), 33.4 (d, AliphC, J_C-P= 16 Hz), 29.6 (d, AliphC, J_C-P= 23 Hz); ¹¹B (128.4 MHz, CD₂Cl₂, 30 ^oC, BF₃-Et₂O): δ 7.4 (s, 1B-S), -2.4 (d, ¹J_B-H= 158 Hz, 1BH), -8.6 (d, ¹J_B-H= 156 Hz, 2BH), -11.6 to -17.7 (m, 6BH); ³¹P{¹H} NMR (162.0 MHz, CD₂Cl₂, 30 °C): δ - 16.3 (s). Calculated for C₁₆H₂₅B₁₀PS: C, 49.46; H, 6.49; found: C, 49.46; H, 6.22. Single crystals suitable for X-ray diffraction studies were grown by slow evaporation from n-pentane in a NMR tube.
