The review presents data on the synthesis, structure, reactivity, and catalytic activity of alkyl derivatives rare earth metals in oxidation state +2 (Sm, Eu, Yb) their analogues containing heavy alkaline (Ca, Sr, Ba). synthetic aspects structural features this unique class organometallic compounds, which contain highly reactive M–C bonds, including alkyl, α-silylmethyl, also benzyl, diphenylmethyl, triphenylmethyl are considered. bibliography includes 157 references.
The first examples of Ln(<sc>ii</sc>) (Ln = Yb, Sm) and Ca [NC<sub>sp3</sub>N] pincer type diarylmethanido complexes were synthesized successfully used as efficient selective precatalyst for intermolecular C–C C–E bond formation.
A series of alkali-metal alkyl complexes containing a tridentate benzhydryl ligand, [2,2′-(4-MeC6H4NMe2)2CH]Li(TMEDA) (1TMEDA), [2,2′-(4-MeC6H4NMe2)2CH]Na(THF)3 (2THF), {[2,2′-(4-MeC6H4NMe2)2CH]K(THF}2 (3THF), and [2,2′-(4-MeC6H4NMe2)2C(SiMe3)]K (5), were synthesized structurally characterized. Smaller Li Na ions form the monomeric 1TMEDA 2THF featuring η4-CCCN coordination [2,2′-(4-MeC6H4NMe2)2CH]− while larger K affords dimeric complex 3THF, in which two different types metal–ligand...
A series of Sc(III) and Y(III) heteroalkyl complexes were synthesized by salt metathesis reactions chloro-bis(diphenylmethanides) {[2,2′-(4-MeC6H3NMe2)2CH]2Ln(μ-Cl)}2 (Ln = Sc, Y) related alkali metal alkyl reagents (MeLi, Me3SiCH2Li, tBuLi, PhCH2K). The molecular structures scandium [2,2′-(4-MeC6H3NMe2)2CH]2ScR (R Me (3), CH2SiMe3 (4), tBu (5)) yttrium [2,2′-(4-MeC6H3NMe2)2CH]2YCH2Ph(THF) (6) established single crystal X-ray analysis, which revealed that diphenylmethanido ligands are κ2-C,N...
