Iron Catalysis in Organic Synthesis: A Critical Assessment of What It Takes To Make This Base Metal a Multitasking Champion

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1273-82-1,Aminoferrocene,as a common compound, the synthetic route is as follows.,1273-82-1

General procedure: Organometallic sulfonamides were prepared following a modification of the procedure described by Alberto and co-workers [41]. An equimolar amount of pyridine was added at room temperature to a solution containing 50mg of P2 or P3 in 7.0mL of anhydrous CH2Cl2. After 15min, the corresponding sulfonyl chloride derivative was added, and the reaction mixture was heated under reflux for 24h. The resulting solution was dried under vacuum. The crude product was purified using silica gel liquid chromatography and a mixture of CH2Cl2/hexane (4:1) as the eluent. All compounds were recrystallized from an acetone/hexane (1:5) mixture by slow evaporation.

As the paragraph descriping shows that 1273-82-1 is playing an increasingly important role.
