52522-40-4, 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. Tris(dibenzylideneacetone)dipalladium-chloroform, cas is 52522-40-4,the catalyst-palladium compound, it is a common compound, a new synthetic route is introduced below.
Under inert gas protection,Tri-tert-butylphosphonium tetrafluoroborate (9.3 g, 0.032 mil,4Eq), tris (dibenzylideneacetone) dipalladium () chloroform adduct (8. 3g, 008 mol, leq) and 200 mlDimethyl sulfoxide was added to the reaction flask,And then slowly dropping to them1M sodium methoxide solution in methanol(32L, 0.032, 0e, 4eq),50 ¡ã C for 15 h.Gloves bag filter,The filter cake was washed with dimethyl sulfoxideThe The filter cake was dried in n-hexane.filter,The filtrate was concentrated and crystallized.filter,The filter cake was washed with a small amount of n-hexane and the filter cake was washed with a small amount of n-hexane and dried to give 3. 27 g of a white solid powder in 80percent yield, elemental analysis: C, 56.17;H, 10. 50; P, 12. 07; Pd, 21.26
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Tris(dibenzylideneacetone)dipalladium-chloroform, 52522-40-4
