Herein, fast Fourier transformation square-wave voltammetry (FFT-SWV) as a novel electrochemical determination technique was used to investigate the electrochemical behavior and determination of Riboflavin at the surface of a nanocomposite modified carbon paste electrode. The carbon paste electrode was modified by nanocomposite containing Samarium oxide (Sm2O3)/reduced gra...

Samarium is an efficient reducing agent, a radical generator in cyclization and cascade addition reaction. Interestingly, samarium metal has crucial impact on numerous C-C C-X (X = hetero atom) bond forming transformations. It been established as exceptional chemo-selective stereoselective reagent. The reactivity of the catalyst/reagent remarkably enhanced presence various additives, ligands so...

A hexakis[2,3,9,10,16,17,23,24-octa(butyloxy)phthalocyaninato] samarium(III)-cadmium(II) sextuple-decker complex (Pc*)Sm(Pc*)Cd(Pc*)Cd(Pc*)Cd(Pc*)Sm(Pc*) (1) with six phthalocyanine ligands bridged by two samarium(III) and three cadmium(II) ions, representing the largest stacked tetrapyrrole metal molecule in the sandwich series in terms of the tetrapyrrole-deck number, has been synthesized and...

The first divalent samarium bis(amidinate) has been prepared and aspects of its novel chemistry, including the preparation of a sterically hindered homoleptic Sm(III) tris(amidinate), explored.

The synthesis of the tetracyclic molecule 2-(9,10-dihydro-9,10-propano-anthracen-9-yl)-N-methylethanamine (2) as a homologue of the antidepressant 1-(9,10-dihydro-9,10-ethanoanthracen-9-yl)-N-methylmethaneamine (1) was described. The key intermediate 9-(prop-2-en-1-yl)-9,10-dihydro-9,10-propanoanthracen-12-one (7) was successfully synthesized via a [4+2] cycloaddition of alpha-bromoacrolein and...

Mechanistic studies show the importance of iodide displacement by additives that accelerate reactions of samarium diiodide. The key feature important for acceleration of reaction rate is the use of proton donors and other additives that have a high enough affinity for Sm(II) to displace iodide yet do not saturate the coordination sphere inhibiting substrate reduction.
