WebThe mechanism of reductions of aldehydes and ketones by samarium iodide is based primarily on mechanisms elucidated for similar one-electron reducing agents. [12] Upon single-electron transfer, a ketyl dimer iv forms. In the absence of protic solvent, this dimer collapses to form 1,2-diols. Web5 nov. 1998 · Samarium(II) iodide (SmI2) has been successfully utilized as a reducing agent for the intramolecular coupling of ketones with nitriles. The use of visible light to promote the reductive coupling represents an improvement over previously reported protocols. The procedure also avoids overreduction of the resulting α-hydroxy ketones. … WebIodine Clock Kinetics. The first reaction, the oxidation, occurs much slower than the reduction, making it the rate-determining step during that first phase of the reaction. Additionally, once the reduction ceases, the oxidation continues to serve as the rate-determining step, as both the formation of the triiodide and the starch complex occur … hidden oaks townhomes lutz fl
