A new biomimetic catalytic oxidation system which employs 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as the catalyst, molecular oxygen as the terminal oxidant and iron(II) phthalocyanine (FeIIPc) as the electron-transfer mediator has been developed. This system can be applied for oxidativedeprotection of PMB ethers, alcohol oxidation, aromatization and α,β-unsaturated aldehyde formation. After
一种新型的仿生催化氧化系统,采用2,3-二氯-5,6-二氰基-1,4-苯醌(DDQ)作为催化剂,分子氧作为末端氧化剂,铁(II)酞菁(Fe II Pc)电子转移介体已经开发出来。该系统可用于PMB醚的氧化脱保护,醇氧化,芳构化和α,β-不饱和醛的形成。将Fe II Pc固定在多壁碳纳米管上后,可以重复使用而不会损失活性。
