Here, by photocatalytic, reversible C–H sampling, we report a functional-group translocation reaction of cyano (CN) groups in common nitriles, allowing for the direct positional exchange between a CN group and an unactivated C−H bond. The reaction shows high fidelity for 1,4-CN ...
‘lock-and-key theory’1,2, enzymes have confined active sites to accommodate their specific reacting substrates, a feature that is typically absent from chemical catalysts. An interesting case in this context is the formation of cyanohydrins from ketones and HCN, as this reaction can be ...
The reaction of Ln(NO3)3(aq) with K3[Fe(CN)6] or K3[Co(CN)6] and 2,2'-bipyridine in water/ethanol led to eight trinuclear complexes: trans-[M(CN)4(mu-CN)2{Ln(H2O)4(bpy)2}2][M(CN)6].8H2O (M = Fe3+ or Co3+, Ln = La3+, Ce3+, Pr3+, Nd3+, and Sm3+). ...
Cycloaddition reaction of 3-cyanoindolizines with dimethyl acetylenedicarboxylate - formation of cycl[3.2.2]azines and 1:2 adducts. 3-Cyano- and 3-cyano-6,8-dimethylindolizines (1a) and (1b) react with dimethyl acetylenedicarboxylate in refluxing toluene in the presence of Pd–C to give the...
PackingGroup: II View all 4.3 Specification 1,1'-Azobis(cyanocyclohexane) (CAS NO.2094-98-6) is self-decomposition or self-ignition, which may be triggered by heat, chemical reaction, friction or impact. It may be ignited by heat, sparks or flames. 1,1'-Azobis(cyanocyclohexane) is an...
such as the Wittig reaction, to introduce the cyanomethylene group into different molecules. CMRP offers a versatile platform for the synthesis of compounds with cyanomethylene functionality, which can be further modified to obtain a wide range of organic compounds. It is important to handle CMRP ...
cyclic voltammetry and ESR that the excitation of the molecules of α,Β derivatives of Β-(5-nitro-2-furyl)-α-cyanoethylene in the radical-anion state by one-electron electrochemical reduction promotes chemical transformation of the other reaction centers, while preserving the nitrofuran group.DOI...

aModel of the reaction centre made by superposition of two of the structures solved in this work. The first structure defines dATP (in yellow) and residue R19 interacting with the α-phosphate (blue); hydrogen atoms were omitted for clarity. The second structure provides catalytic ions A and ...
3.2.3. Real time polymerase chain reaction The novel compound 7 was selected from this new series for molecular studies on one of the three sensitive cell lines (colon carcinoma) as it illustrated high sensitivity and cytotoxicity toward the tested cell line as mentioned in the previous section....
