As a common heterocyclic compound, it belongs to catalyst-palladium compound, name is Bis(tri-tert-butylphosphine)palladium, and cas is 53199-31-8, its synthesis route is as follows.
B. Synthesis of 3-(1-pyrrolidinyl)phenol 7g (30 mmol) of 1-Bromo-3-methoxymethoxy-benzene from step A and 2,5 g (35 mmol) of pyrrolidine were dissolved under argon in 60 mL of toluene. Then, 0.15 g (0.3 mmol) of bis(tri-t-butylphosphine)palladium(0), 2,5g KOH und 0,6g (0,15 mmol) cetyltrimethylammoniumbromid were added, and the reaction mixture was heated at 80 C. At the end of the reaction, the reaction mixture was poured into 200 mL of ethyl acetate, and the organic phase was extracted with 1 N sodium hydroxide solution and then dried with magnesium sulfate. The solvent was distilled off in a rotary evaporator, and the residue was purified on silica gel using heptane/ethyl acetate (8/0,8). The product thus obtained was dissolved in 15 mL of ethanol and mixed with 10 mL of a 2.9 molar solution of ethanolic hydrochloric acid.
53199-31-8, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,53199-31-8 ,Bis(tri-tert-butylphosphine)palladium, other downstream synthetic routes, hurry up and to see
