Lanthanides and actinides: Annual survey of their organometallic chemistry covering the year 2012

摘要: Abstract This review summarizes the progress in organo- f -element chemistry during year 2012. A continuing trend organolanthanide research is a strong emphasis on applications of complexes homogeneous catalysis and materials science. Reactive lanthanide alkyl supported by ligands other than cyclopentadienyl rings also continue to attract interest. Currently, study organo-rare-earth-based SMMs another exciting topic chemistry. Notable among highlights synthesis first molecular holmium erbium +2 oxidation state which have been generated reducing Cp′ 3 Ln (Cp′ = C 5 H 4 SiMe ; Ln = Ho, Er) with KC 8 presence 18-crown-6 Et 2 O at −35 °C. The direct P activation using scandium yttrium has achieved for time under mild conditions. Two novel n -containing products, [(NN fc )Sc] 7 , were isolated from reactions arene ( μ -naphthalene)[(NN -anthracene)[(NN (NN  = 1,10′-fc(NSi t BuMe ) fc = ferrocenylene). steady increase activities focussed endohedral metallofullerenes observed Highly remarkable this field was discovery that complexation TiCl can provide an efficient route separation purification empty fullerenes large scale.
