α-羟基酸锰配合物(H2 L)参与了木质素的氧化降解过程.在这篇文章中,我们评估了锰(III)和锰(IV)α-羟基酸化合物使用乳酸(H 2 Lc),2-羟基-2-乙基丁酸(H 2 HEB),和2-羟基异丁酸(H 2 HIB)的化学。探索了氧化和还原两种方法合成(Cat)3 [(Cat)MnIV 2L 6 ]、(Cat)3 [MnIII 2(L)4 HL]和(Cat)2 [MnIII(L)2 HL]化合物
Manganese complexes of α-hydroxy acids (H 2 L) have been implicated in the basidomycete oxidative degradation pathway of lignin. In this contribution, we evaluate the chemistry of manganese (III) and manganese (IV) α-hydroxy acid compounds using lactic acid (H 2 Lc), 2-hydroxy-2-ethylbutyric acid (H 2 HEB), and 2-hydroxyisobutyric acid (H 2 HIB). Both oxidative and reductive methodologies to give compounds of stoichiometry (Cat) 3 [(Cat)Mn IV 2 L 6 ], (Cat) 3 [Mn III 2 (L) 4 HL] and (Cat) 2 [Mn III (L) 2 HL] have been explored
