An efficient iron-promoted alkylation of indoles with enamides has been accomplished under mild reaction conditions. The reaction proceeded with remarkable regioselectivity leading exclusively to substitution by indoles at α-position of enamides.

Pseudomonas aeruginosa (GRC1) isolated from potato rhizosphere, grew better on succinate medium than tryptic soy medium and produced hydroxamate type of siderophore in iron-deficient succinate medium. When the strain GRC1 was grown in the presence of different metal ion compounds, viz. ZnSO4, MnSO4, MnCl2 and FeCl3 at 6 and 12 microM concentrations individually, ZnSO4 (12 microM) promoted sider...

The culture conditions for the enhanced mycelial growth of Ramaria botrytis was investigated. The optimal temperature and pH for the mycelial growth were 24℃ and 5.0, respectively. It was shown that starch was best of several carbon sources in Czapek-Dox medium as a minimal medium for the enhanced mycelial growth. Organic nitrogen sources were better than inorganic ones for mycelial growth. The...

While iron-catalyzed Kumada cross-coupling reactions with simple iron salts have been known since the early 1970s, the nature of the in situ-formed iron species remains elusive. Herein, we report the synthesis of the homoleptic tetralkyliron(III) ferrate complex [MgCl(THF)5][FeMe4] from the reaction of FeCl3 with MeMgBr in THF. Upon warming, this distorted square-planar S = (3)/2 species conver...

The aim of this research was to explore the removal Red G and Bordeaux B dyes from water using a packed bed column with conventional carbon (C-conv) iron-modified activated (C-FeCl3). bands increased in C-FeCl3, corresponding groups already existing C-conv, such as C = C-C, appearance new groups, C-O, C-Cl, Fe-Cl Fe-O. total ash content (CT) CT (10.53 ± 0.12 8.98 0.21)% for C-conv respectively....

Dilute FeCl3 and Fe(NO3)3 solutions degraded parathion to paraoxon and p-nitrophenol. Initial hydrolysis products of iron appeared to have the greatest catalytic activity which decreased as these hydrolysis products aged. The Fe3+ ion was less catalytically active than its hydrolysis products for parathion degradation. pH was not a factor in parathion degradation in this study. AlCl3 solutions ...

The conceptually construction of axially chiral indolostilbenesi.eN-(2-{(E)-2-[2'-(1-Acetyl-1H-indol-2-yl)-3'chloro4,4',6,6'-tetramethoxy[1,1'-biphenyl]-2yl]ethenyl}phenyl)acetamide and N-(2-{(E)-2-[2'-(1-Acetyl-1H-indol-2-yl)-3'-chloro-2,4',6,6'tetramethoxy[1,1'-biphenyl]-4-yl]ethenyl}phenyl) acetamide are described in this paper. These structure, were obtained by the tactical combination of p...
