Synthesis organolanthanide complexes

Although the structures of these species were not determined, this metal vapor chemistry clearly showed that unsaturated hydrocarbons were viable reagents for lanthanides. Furthermore, this high energy technique showed that new regimes of organolanthanide complexes were accessible under the appropriate conditions. In addition, attempts to understand the synthesis of the products in reac-...

Although the polymerization prowess of organolanthanide complexes has been known for some time, efforts to apply these catalysts to small molecule synthesis have only recently begun. The selectivity of these metallocenes is predominantly steric in nature, and they are compatible with a wide variety of organic functional groups. A review of their use in olefin hydrogenation,hydrosilylation, and polyene cydization with emphasis on chemoselectivity and diastereoselectivity is presented here. The various ways in which the catalysts and reagents can be tuned to produce the desired products is also discussed.

The aminoaUene hydroamination/cyclization reactions are highly diastereoselective and can provide concise routes to synthesize some natural products (Scheme 3). Using chiral organolanthanide complexes as catalysts, enantioselec-tive hydroamination/cychzation reactions are achieved, which provide a convenient route for the synthesis of chiral amines from simple, readily available prochiral substrates in a single step. 

Oxygen-containing heterocycles are abundant in nature and are important in fine chemicals. The addition of alcohols across unsaturated C-C bonds represents an atom-economical and direct route for the synthesis of these cyclic ethers. Hydroalkoxylation transformations mediated by a wide range of transition-metal and alkali-metal catalysts yield a variety of vinyl ethers. Organolanthanide complexes offer an alternative agent for the efficient and highly selective synthesis of both aliphatic and vinyl ethers with selectivities often complementary to those of transition-metal catalysts. 

Main Group, Lanthanides and Actinides - In the series of papers Studies on Organolanthanide Complexes several topics have been covered the formation of ion-pair complexes of the type [ Na.phenan3 Cp]LnCl phenan] (phenan = 1,10-phenanthroline), the synthesis and structural chemistry of bismethoxylethylcyclopentadienyl complexes, and furan bridged bis-cyclopentadienyl complexes. A number of synthetic papers have also appeared in the area the synthesis of cyclooctatetraenyl-cyclopentadienyl sandwich complexes, " " the...
