Adding a certain compound to certain chemical reactions, such as: 52522-40-4,Tris(dibenzylideneacetone)dipalladium-chloroform, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 52522-40-4,52522-40-4
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
According to the analysis of related databases, 52522-40-4, the application of this compound in the production field has become more and more popular.
