The title compound, P(C10H7)3·0.5CHCl3, was isolated after the unsuccessful reaction of KSeCN and tris-(naphthalen-1-yl)phosphane. The solvent mol-ecule is disordered about an inversion center. The effective cone angle of the phosphine is 203°. In the crystal, weak C-H⋯Cl and C-H⋯π inter-actions are observed.
In the title compound, C(17)H(14)NPSe, the P atom has a distorted tetra-hedral environment resulting in an effective cone angle of 163°. In the crystal, C-H⋯Se/N/π inter-actions are observed.
New naphtho[2,1,8,7-klmn]xanthene and benzo[kl]xanthene-based intramolecular phosphane–borane frustrated Lewis pairs (FLPs) were investigated in catalyzed H2 activation CO2 hydrogenation processes. According to DFT predictions at the B3LYP-D3 level, presence of rigid scaffolds increased P···B distances FLPs lead a remarkable drop energy barrier for (by up 19.2 kcal mol−1, compared parent dimeth...
Palladium-catalyzed amination reactions of aryl halides have undergone rapid development in the last 12 years, largely driven by the implementation of new classes of ligands. Biaryl phosphanes have proven to provide especially active catalysts in this context. This Review discusses the application of these catalysts in C-N cross-coupling reactions in the synthesis of heterocycles and pharmaceut...
The title compound, C21H15O4P·0.5C4H8O, contains an ordered phosphane oxide in a general position and a tetra-hydro-furan solvent mol-ecule disordered about a twofold axis. All three aldehyde substituents are nearly coplanar with their attached benzene rings, with C-C-C-O torsion angles in the range 1.64 (17)-4.24 (19)°. All three have different conformations with respect to the P=O group, one ...
The title compound, [Fe(NO)(2)(C(21)H(21)P)(2)], belongs to the family of metal dinitrosyl compounds with the general formula Fe(NO)(2)(L)(x), referred to collectively as 'dinitrosyl iron compounds' (DNICs). Herein we report the structure of a dinitrosyl iron diphosphane complex, [Fe(NO)(2)L(2)], with L = P(C(6)H(4)-p-CH(3))(3). There are two crystallographically independent but chemically equa...
