Synthetic procedure: See article for the definitive version of this procedure and for full experimental details.
A typical experimental procedure is given for compound 3a′. 1H NMR (400.1 MHz, CD2Cl2, 30 °C): δ 7.82-6.94 (bm, 34H, ArH), 3.24 – 2.46 (bm, 8H, AlkH); 19F NMR (376.5 MHz, CD2Cl2, 30 °C) δ -62.9 (m, 24F, BArF), -130.1 (m, 2F, ArF), -133.8 (m, 2F, ArF), -134.4 (m, 2F, ArF), -138.0 (m, 2F, ArF). 31P {1H} NMR (162.0 MHz, CD2Cl2, 30 °C): δ 43.4 (d, 2JP-P=15 Hz 1JP-Pt=3454 Hz), 9.9 (d, 2JP-P=15 Hz, 1JP-Pt=3369 Hz). HRMS (ESI): m/z calcd for C40H30ClF8P2PtS2 [M+BArF]+: 1018.0473, found: 1018.0514. Single crystals suitable for X-Ray studies of the analogous complex 3i-BF4 (obtained from monoabstraction reaction with AgBF4) were grown by slow diffusion of diethyl ether, layered on top of a dichloromethane solution of 3i-BF4 in a NMR tube.
