QM/MM calculations of the deacylation-3s structure confirm the “attack” conformation as energetically favorable. (a) The reaction scheme for the deacylation step of the “attack” conformation according to the prevailing model. INT: acyl adduct intermediate. TI: tetrahedron intermediate. PC: produ...
The Schmidt rearrangement, a reaction that enables C-C or C-H σ bond cleavage and nitrogen insertion across an aldehyde or ketone substrate, is one of the most important and widely used synthetic tools for the installation of amides and nitriles. Howeve
To synthesize the compounds Ethyl methyl ether, tert-Butyl methyl ether, Anisole, and Phenetole, we can utilize the Williamson Ether Synthesis method. Below is a step-by-step outline for the synthesis of each compound:(i) Synthesis of E
A: The gray band shows how the standard entropy changes as the substrate moves along the reaction coordinate through an entire metabolic pathway. It begins with a black segment representing (on the far left) the equilibrated state of the parent substrate. Following the band to the right shows ...
The operation principle of the amperometric sensors has already been discussed. A positive potential is applied to the inner electrode. Due to the applied potential, steam reacts at the outer electrode according to the following reaction. H2O+2e−→H2+O2−H2O+2e−→H2+O2− (9) Steam...
The reaction between iron (oxyhydr)oxides and dissolved sulfide is a surface-controlled process and has been suggested to proceed via the following reaction sequence (Dos Santos Afonso and Stumm, 1992): (I) Surface complex formation: >FeIIIOH + HS−⇔k−1k1>FeIIIS−+H2O(II) Electron ...
