Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. Tris(dibenzylideneacetone)dipalladium-chloroform,52522-40-4, This compound has unique chemical properties. The synthetic route is as follows.,52522-40-4
52522-40-4, A mixture of 55 mg (0.53 mmol) Pd2(dba)3CHCl3 and 200 mg(0.11 mmol) of [Mo3S4Cl3(dnbpy)3]PF6 in 20 ml of dichloromethanewas refluxed for 1 day. An excess of hexane was layeredonto the resulting brown solution to give brown crystals of 3.Yield: 113 mg (57percent). Anal. Calcd for C84H132N6Cl4Mo3S4Pd: C53.4, H 7.0, N 4.5, S 6.8.
