In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact.52522-40-4, Tris(dibenzylideneacetone)dipalladium-chloroform it is a common compound, a new synthetic route is introduced below.52522-40-4
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.
As the rapid development of chemical substances, we look forward to future research findings about 52522-40-4
