早期镧系元素的新未溶解茂金属
New unsolvated metallocenes of early lanthanides,
(Cp4i)2Sm, COTSmCp4i, and COTNdCp41 (Cp4i = C5HiPr4) have been
prepared and fully characterised, including X-ray structural analysis: the absence of ancillary base in these complexes is not only the consequence of steric effects; these results bring up the debated question of electronic control in organolanthanide chemistry.
