Hydroxylation of benzene in the system vanadium(V)-hydrogen peroxide-acetic acid

Recent Progress in B—H Bond Functionalization of nido-Carboranes

“…卤化产物也可由巢式-碳硼烷与卤代 丁二酰亚胺(X＝Cl, Br, I)反应得到且收率良好. Rudakov 课题组 [10] 利用电化学方法合成单碘和单溴衍生物. 该 反应使用巢式-碳硼烷与碘化钠溶于无水乙醇中, 电流 密度为 0.1 A/cm 2 , 电解 3 h, 以 95%收率得到目标产物 (Scheme 2).…”

Benzene Hydroxylation and Simultaneous Extraction of Phenol in Two Membrane Contactors Made with Three-Compartment Cells

“…This one-step process attained a phenol selectivity of 80–97%, benzene conversion of 2–16% below 250 °C, and a phenol yield of 1.5 g ph g cat –1 h –1 at 150 °C. Some papers in the literature considered H 2 O 2 as the oxidant in benzene hydroxylation to phenol. − Bianchi et al reported a water–acetonitrile (1:1) biphasic reaction medium in which the produced phenol was extracted into the organic phase and the Fenton catalyst was soluble in the aqueous phase. Benzene conversion of 8.6% and a selectivity to phenol of 97% were attained in such a system.…”

Density Functional Theory Study on the Re Cluster/HZSM-5 Catalysis for Direct Phenol Synthesis from Benzene and Molecular Oxygen: Active Re Structure and Reaction Mechanism

“…Therefore a direct phenol synthesis from benzene with molecular oxygen as a sole oxidant is desirable from the viewpoints of an environment-friendly green process and economical efficiency. In previous studies, many oxidants have been used for direct phenol synthesis from benzene, such as O 2 [1][2][3][4][5][6], H 2 O 2 [7][8][9][10][11][12][13][14][15], N 2 O [16][17][18][19][20][21][22][23][24][25], H 2 ? O 2 [26,27], air/CO [28], and O 2 /H 2 O [29].…”
