TL;DR: In this article, the isolation, structural characterization, and reactivity of a series of lanthanide ketyl complexes, which are generated by reactions of benzophenone and fluorenone with several different types of reducing agents including Ln(OAr)2(L)x (Ar = C6H2-tBu2-2,6-Me-4), (C5Me5)2Ln(THF)2 (Ln = Sm, L = THF, x = 3; 1b: Ln = Yb, L

TL;DR: In this article, an asymmetric methoxyselenenenylation of alkenes was studied using some chiral ferrocenylselenium compounds which were prepared from chiral amino-substituted amine, sulfoxide, oxazoline, and pyrrolidine.

TL;DR: In this paper, a bis-substituted cyclopentadienyl ligand of bridged structure and a mixture of the compound with an aluminoxane are provided, each useful as catalyst component for stereoregular olefin polymerization.

TL;DR: Pyridines, 1,2-dithiopyrones, and N-methyltetraphenyl-2-thiopyridone are synthesized by the rection of cobaltacyclopentadiene complexes with nitriles, carbon disulphide, and methyl isothiocyanate respectively.

TL;DR: Synthesis of a new class of heteroleptic samarium aryloxide complexes has been achieved by the use of homoleptic Samarium(II) bis(aryloxide) Sm(OAr)(2)(THF)(3) (1, Ar = C(6)H(2)Bu(t)(2)-2,6-Me-4) as a starting material, which is easily obtained by reaction of Sm(N(SiMe(3))(
