TL;DR: The first P, C -cyclopalladated complex with planar chirality was prepared by direct cyclopalladation of prochiral di- tert -butyl(ferrocenylmethyl)phosphine as mentioned in this paper.
Abstract: The first P , C -cyclopalladated complex with planar chirality was prepared by direct cyclopalladation of prochiral di- tert -butyl(ferrocenylmethyl)phosphine. Resolution of the racemic dimer was achieved through separation of its diastereomeric ( S )-prolinate derivatives. The palladacycle structure was confirmed by the 1 H NMR spectra of the dimer and its triphenylphosphine adduct and an X-ray diffraction study of the racemic dimeric complex. The absolute configuration of the planar chirality was determined by an X-ray diffraction investigation of one of two diastereomers of the ( S )-prolinate derivative.

TL;DR: In this article, the crystal and molecular structures of MoO2Cl2 complex with acetoacet-2-toluidine (HL) were determined by X-ray diffraction analysis.
Abstract: A series of MoO2Cl2 complexes with acetoacetanilide derivatives were synthesized and studied by IR spectroscopy. The crystal and molecular structures of the MoO2Cl2 complex with acetoacet-2-toluidine (HL) were determined by X-ray diffraction analysis. The monoclinic crystals involved are a = 7.621(7) A, b = 9.498(3) A, c = 19.980(9) A, β = 95.16(7)°, V = 1440(2) A3, Z = 4, and space group P21/n. The coordination polyhedron of the Mo atom is a distorted octahedron with two O oxoatoms in the cis-position relative to each other, two Cl atoms in the trans-positions, and two O atoms (HL) in the trans-positions to O(oxo).

TL;DR: The molecular and crystal structure of the complex of cupric bromide with 1,5-diphenyl-3,7-dimethyl-3-7-diazabicyclo[3.3.1]nonan-9-ones was studied in this paper.
Abstract: The molecular and crystal structure of the complex of cupric bromide with 1,5-diphenyl-3,7-dimethyl-3,7-diazabicyclo[3.3.1]nonan-9-ones was studied. The geometry of the complexes of bispydines with cupric halides was shown to depend on the substituent at the nitrogen atom.

TL;DR: In this article, the reaction of trifluoromethyl-containing enones with thiophenol derivatives has been studied, and the results of these reactions lead to 3-trifluoroacetyl-substituted 2H-thiochromenes.
Abstract: The reaction of trifluoromethyl-containing enones with thiophenol derivatives has been studied. Reactions with 4-methylthiophenol proceed with the formation of either ketosulfides or a pyran derivative. Reactions of trifluoromethyl-containing enones with 2-mercaptobenzaldehyde lead to 3-trifluoroacetyl-substituted 2H-thiochromenes.
