Glycollates of samarium reactions of samarium isopropoxide with glycols

Inorganica Chimica Acta, 1967
Abstract The reactions of samarium isopropoxide with glycols e.g., ethylene glycol (ethane 1,2-diol) propylene glycol (propane 1,3-diol),1,2 dimethyl ethylene glycol (butane 2,3-diol), hexylene glycol (2 methyl pentane 2,4-diol), neopentyl glycol, and pinacol 2,3 dimethyl butane 2,3-diol) in equimolecular ratios have been carried out in benzene.

Radioactivity of Samarium

Nature, 1932
THE discovery that the radioactivity of potassium is due to a minor isotopic constituent, suggests the idea that other common elements may also have radioactive isotopes present in small amounts. This line of thought induced us to investigate the properties of samarium and we found this element to be markedly radioactive.

Samarium Diiodide/Samarium-Mediated Deoxygenative Hydrosilylation of Ketones

The Journal of Organic Chemistry
The first deoxygenative hydrosilylation of ketones promoted by samarium diiodide and samarium has been reported. In this approach, secondary alkyl silanes are synthesized from unactivated ketones and chlorosilanes in one step. The carbonyl group of ketones is activated by SmI2-mediated single-electron transfer process, which follows a deoxygenative ...

Neutron Cross Sections of Samarium-147 and Samarium-150

Nuclear Science and Engineering, 1974
The total neutron cross sections of samarium highly enriched in the 147Sm and 150Sm isotopes have been measured from 0.01 eV to 1.2 keV.

Samarium Diiodide/Samarium‐Mediated Deoxygenative Hydroborylation of Aldehydes

European Journal of Organic Chemistry
AbstractA samarium diiodide/samarium‐mediated direct deoxygenative hydroborylation of aldehydes with hydroborate ester has been reported. In this method, unactivated aldehydes and hydroborate ester have been employed as starting materials for the synthesis of primary alkyl borate esters.

Photodisintegration of samarium

Il Nuovo Cimento, 1956
In order to study the photodisintegration of Sm induced by irradiation with X-rays, discs of pressed Sm2O3 were exposed to the irradiation with X-rays from the 22 MeV Betatron of the Laboratrio de Fisica Nuclear of the University of Sao Paulo. In the present paper the results of the experiments are related.
