Adding a certain compound to certain chemical reactions, such as: 5164-76-1, name is Dimethyl pent-2-enedioate, belongs to esters-buliding-blocks compound, 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 5164-76-1, COA of Formula: C7H10O4
General procedure: The crude aryl diazonium tosylate 9 thus obtained was dissolved or suspended in MeOH (30 mL). Dimethyl glutaconate (1.45 mL, 10.0 mmol) and Pd(OAc)2 (112 mg, 0.5 mmol) were successively added while stirring. After stirring at r.t. for 15 h, the mixture was concentrated under reduced pressure and partitioned between CH2Cl2 (40 mL) and H2O (25 mL). The organic layer was washed with brine, dried (Na2SO4), and concentrated in vacuo. The residue was briefly fractionated on SiO2 using CH2Cl2 or CH2Cl2- acetone (5:1) as eluent. Fractions containing arylation product were pooled and concentrated to give compound 10 of at least 90% purity (according to 1H NMR analysis). It was used in the next step without further purification.
