Application of 7681-82-5, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 7681-82-5 as follows.
A mixture of the platinum vinylcarbene 8 (200mg, 0.261mmol) and NaI (391mg, 2.61mmol) in THF (15mL) was stirred for 5minat room temperature. All volatiles of the reaction mixture were removed under vacuum. The residue was extracted with DCM (5mL×2) and dried under reduced pressure to provide complex 14A as a yellow solid. Yield: 95% (235mg, 0.247mmol). 1H NMR (400MHz, CD2Cl2): delta 7.84 (d, J=1.8Hz, 1H, CH=CPh2) 7.63-7.68 (m, 6H), 7.38-7.49 (m, 19H), 5.04 (q, J=7.1Hz, 2H, CH2), 1.09 (t, J=7.1Hz, 3H, CH3). 31P{1H} NMR (162MHz, CD2Cl2): delta 8.6 (s, JPtP=2118.8Hz). 13C{1H} NMR (100MHz, CD2Cl2): delta 269.9 (d, J=141.3Hz, Pt=C), 154.9 (d, J=2.5Hz, HC=CPh2), 139.6 (ipso-CPh2), 138.3 (ipso-CPh2), 134.6 (d, J=10.8Hz, o- or m-PPh3), 133.5 (d, J=8.0Hz, HC=CPh2), 130.9 (d, J=50.0Hz, ipso-PPh3), 130.3, 129.6 (d, J=1.9Hz, p-PPh3), 129.2, 129.0, 128.0, 127.8, 127.2, 127.0 (d, J=9.8Hz, o- or m-PPh3), 79.2 (d, J=3.5Hz, CH2), 12.1 (CH3).
