This review summarizes the progress in organo-f-element chemistry during the year 2006. A continuing trend in organolanthanide research is a strong emphasis on applications of organolanthanide complexes in homogeneous catalysis and, to a lesser extent, materials science. Only little more than 10% of all relevant papers published in 2006 were in the area of organoactinide chemistry, although the latter has produced some truly spectacular results.
