Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Nippon Kagaku Zasshi called Reactions of haloferrocenes with organolithium compounds, Author is Sonoda, Akio; Moritani, Ichiro, which mentions a compound: 1273-73-0, SMILESS is Br[C-]12[Fe+2]3456789([C-]%10C6=C7C8=C9%10)C1=C3C4=C25, Molecular C10BrFe, Reference of Bromoferrocene.

Reactions of BuLi or PhLi with chloroferrocene (I), 1,1′-dichloroferrocene (II), and bromoferrocene (III) were investigated. I (0.802 g) in 25 ml Et2O treated with 200 millimoles. BuLi in Et2O and quenched with H2O gave 0.033 g ferrocene (IV) and 0.534 g I. Lithiation of 0.870 g I followed by carbonation and esterification afforded 0.398 g Me 2-chloroferrocenecarboxylate (V) and 0.051 g di-Me 2-chloroferrocene-1,1′-dicarboxylate. Similarly I and PhLi gave 21% V. Heating I and PhLi 4.5 hr and quenching with H2O afforded 50% I, 8% IV, and 24% phenylferrocene (V). However no ferrocyne was detected in attempted capture with some dienes. Similarly lithiation of II followed by carbonation and esterification gave meso and racemic forms, m. 117-17.5° and 110-11°, of di-Me 2,2′-dichloroferrocenedicarboxylates in 48% yield. The reaction of III with BuLi at -78° followed by quenching with H2O gave 36% IV and 37% IV, whereas lithiation at room temperature gave 99% IV. Treating III with PhLi also afforded small amount of V. Lithiation at the 2-position is favored in the case of the Cl compound whereas Br-Li exchange is favored in the case of the Br compound I lithiated with BuLi and treated with HgBr2 gave bis(2-chloroferrocenyl)mercury (VI), m. 219-20°. Similarly bis(2,1′-dichloroferrocenyl)mercury was prepared Attempted capture of ferrocyne by heating VI in tetracyclone ended in failure, the product being IV.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-(7-Bromo-1H-indol-3-yl)acetic acid, is researched, Molecular C10H8BrNO2, CAS is 63352-97-6, about Auxin-binding site in wheat shoots: interactions between indol-3-ylacetic acid and its halogenated derivatives.Product Details of 63352-97-6.

The specificity of IAA-binding site from wheat shoots was investigated in an attempt to confirm its receptor function. Several monofluoro-, monochloro-, dichloro-, and monobromo-substituted indol-3-ylacetic acids were allowed to displace 14C-IAA from the binding site. Displacement abilities of these halogenated IAAs were closely related to their activities in wheat coleoptile straight growth biotest. This finding indirectly confirms the physiol. significance of this binding site.

The redox behavior and kinetic parameters of five ferrocene derivatives were investigated in 1M LiPF6 in 50:50 volume% ethylene carbonate:Et Me carbonate, a typical electrolyte used in lithium-ion batteries. Using cyclic voltammetry and rotating disk electrode voltammetry techniques, the effect of electron donating and withdrawing substituents on each derivative was evaluated from the view point of the Hammett substituent constant We found that electrochem. rate constants of the ferrocene derivatives can be related to the Hammett equation which gives an accurate approximation for predicting the oxidation potential of redox shuttles when changes are desired in their electron donating and electron withdrawing properties by means of functional group substitution. Our results show that the exchange c.d. and reaction rate for oxidation decrease as the electron withdrawing property of the substituent increases. It is also shown that electron donating and electron withdrawing property of a substituent affect the exchange c.d. and electrochem. oxidation reaction rate obeying a trend opposite to that of the Hammett substituent constants (σ). The correlations found here are expected to improve the ability to systematically design chem. overcharge protection reagents through judicious substitution of functional groups on redox shuttles.
