Synthetic procedure: See article for the definitive version of this procedure and for full experimental details.

A typical experimental procedure is given for compound 2a. ¹H NMR (400.1 MHz, CD₂Cl₂, 30 °C): δ 7.91-7.64 (m, 3H, ArH), 7.61-7.06 (m, 7H, ArH) 3.22-1.43 (bm, 13H, cage-BH, alkyl-CH), 2.05 (s, 3H, BCH), 1.98 (s, 3H, BCH); ¹¹B NMR (128.4 MHz, CD₂Cl₂, 30 °C, BF₃-Et₂O): δ -0.2 (s, 1B, B-S), -5.1 to -14.6 (bm, 9BH); ³¹P {¹H} NMR (160.2 MHz, CD₂Cl₂, 30 °C): δ 40.9 (s, J_P-Pt = 3642 Hz). HRMS (ESI): m/z calcd for C₁₈H₂₉B₁₀ClPPtS [M-Cl]⁺: 646.2067, found: 646.2051. Calculated for C₁₈B₁₀H₂₉Cl₂PPtS: C, 31.67; H, 4.28; found: C, 32.06; H, 4.30. Single crystals suitable for X-ray diffraction studies were grown by slow evaporation from CH₂Cl₂ in a NMR tube.
