Ml. Kuhlman et Ra. Flowers, Aggregation state and reducing power of the samarium diiodide-DMPU complexin acetonitrile, TETRAHEDR L, 41(42), 2000, pp. 8049-8052
The aggregation state of SmI2 and the reducing power of SmI2 and its DMPU c
omplex were investigated employing vapor pressure osmometry (VPO) and cycli
c voltammetry (CV), respectively. The aggregation number for SmI2 in aceton
itrile was found to be 1.03+/-0.07 over the entire concentration range stud
ied indicating that SmI2 is monomeric. The CV study showed that DMPU enhanc
es the reducing power of SmI2 in acetonitrile but that the resulting comple
x is not as powerful as the SmI2-HMPA complex in THF. The CV study also sho
wed that solvent could alter the reducing power of SmI2. (C) 2000 Elsevier
