52522-40-4, Tris(dibenzylideneacetone)dipalladium-chloroform is a catalyst-palladium compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
The catalyst was prepared according to the reported procedure in the literature [36], which briefly will explain here. A solution containing Pd2(dba)3.CHCl3 (0.149g, 0.15mmol) and Pt(Ph2Ppy)2Cl2 (0.237g, 0.30mmol) in 50mL of dichloromethane was heated in reflux condition for 2h under nitrogen atmosphere. Then the solution was cooled to room temperature, and diethyl ether was added slowly to precipitate a greenish brown solid. The precipitate was collected by filtration and dried by vacuum. Yield 0.085g, 73percent. C34H28Cl2N2P2PdPt (MW=898.95): calcd. C 45.43, H 3.14, N, 3.12. Found: C 45.21, H 3.13, N 3.48. 1H NMR in CDCl3: delta 9.61?9.50 (m, 2H), 7.75?7.32 (m, 24H), 6.78?6.67 (m, 2H). 31P NMR in CDCl3: delta?7.6 (d, 3JPaPb=14Hz, 1JPtP=4047Hz, 1P, Pa bonded to the Pt), 32.4 (d, 3JPaPb=14Hz, 1JPtP=111Hz, 1P, Pb bonded to the Pd) ppm.
The synthetic route of 52522-40-4 has been constantly updated, and we look forward to future research findings.
