TL;DR: In this paper, heavy alkaline earth (Ca, Sr, Ba) di-iodides with metallic potassium in tetrahydrofuran precipitates finely divided metal powders which react rapidly with triphenylmethyl chloride, Me5C5H, fluorinated acetylacetones, and phenols to generate the corresponding alkyl metal halides, metallocenes, acetylacetonates, and aryl oxides.
Abstract: Reduction of heavy alkaline earth (Ca, Sr, Ba) di-iodides with metallic potassium in tetrahydrofuran precipitates finely divided metal powders which react rapidly with triphenylmethyl chloride, Me5C5H, fluorinated acetylacetones, and phenols to generate the corresponding alkyl metal halides, metallocenes, acetylacetonates, and aryl oxides.

TL;DR: In this paper, a metal-organic complex of the formula MAYX is defined, wherein M is a y-valent metal; A is a monodentate or multidentate organic ligand coordinated to M which allows complexing of MAy with X; y is an integer having a value of 2, 3 or 4; each of the A ligands may be the same or different.
Abstract: A metalorganic complex of the formula MAYX, wherein M is a y-valent metal; A is a monodentate or multidentate organic ligand coordinated to M which allows complexing of MAy with X; y is an integer having a value of 2, 3 or 4; each of the A ligands may be the same or different; and X is a monodentate or multidentate ligand coordinated to M and containing one or more atoms independently selected from the group consisting of atoms of the elements C, N, H, S, O and F. The metal M may be selected from the group consisting of Cu, Ba, Sr, La, Nd, Ce, Pr, Sm, Eu, Th, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Bi, Tl, Y, Pb, Ni, Pd, Pt, Al, Ga, In, Ag, Au, Co, Rh, Ir, Fe, Ru, Sn, Li, Na, K, Rb, Cs, Ca, Mg, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, and W. A may be selected from the group consisting of β-diketonates and their sulfur and nitrogen analogs, β-ketoesters and their sulfur and nitrogen analogs, cyclopentadienyls, alkyls, perfluoroalkyls, alkoxides, perfluoroalkoxides, and Schiff bases. X may for example comprise a ligand such as tetraglyme, tetrahydrofuran, bipyridine, crown ether, or thioether.
