Abstract Phosphinate and phosphane substituted hierarchical helicates have been prepared, the phosphinate derivatives could be characterized in crystal. The helicate with substituents was submitted to an orientating study on catalysis, showing its potential act as chelating ligand for generation of active rhodium‐based hydrogenation catalysts.

The title compound, [Cu(C(16)H(11)BrN(2))(C(18)H(15)P)(2)]BF(4), is composed of one Cu(I) atom, one 6-(4-bromo-phen-yl)-2,2'-bipyridine (L) ligand, two triphenyl-phosphane mol-ecules and one tetra-fluoridoborate anion. The Cu(I) ion is four-coordinated in a distorted tetra-hedral configuration by two N atoms from L and two P atoms from triphenyl-phosphane ligands. In the L ligand, the two pyrid...

In the centrosymmetric mol-ecular structure of the title compound [Pt(2)(C(6)H(14)P)(2)H(2)(C(9)H(21)P)(2)], each Pt(II) atom is bound on one side to a phosphane ligand (PiPr(3)) and a hydrido ligand. On the other side, it is bound to two phosphanide ligands (μ-PiPr(2)), which engage a bridging position between the two Pt(II) atoms, forming a distorted square-planar structure motif. The Pt⋯Pt d...

In the title compound, [PtCl2(C21H21O3P)2]·2C3H6O, the asymmetric unit contains a Pt(II) ion situated on an inversion center, one chloride anion, one tris-(4-meth-oxy-lphen-yl)phosphane (L) ligand and one acetone solvent mol-ecule. The Pt(II) ion is coordinated by two P atoms [Pt-P = 2.3196 (5) Å] from two L ligands and two chloride anions [Pt-Cl = 2.3075 (5) Å] in a distorted square-planar geo...

The title complex, [Cu(3)WBrOS(3)(C(18)H(15)P)(3)], a neutral heavily distorted cubane-like W/S/Cu cluster, was self-assembled from ammonium trithio-tungstate(VI), cuprous bromide and triphenyl-phosphane in N,N-dimethyl-formamide. The average Cu-Br, Cu-S and W-μ(3)-S bond lengths are 2.731 (2), 2.318 (2) and 2.256 (2) Å, respectively, in the distorted cubane-like skeleton. The W atom exhibits t...

A series of phosphanes with imidazolyl substituents were prepared as hemilabile PN ligands. The corresponding gold(I) complexes were tested as bifunctional catalysts in the Markovnikov hydration of 1-octyne, as well as in the synthesis of propargylamines by the three component coupling reaction of piperidine, benzaldehyde, and phenylacetylene. While the activity in the hydration of 1-octyne was...

The title compound, [Mo(C(5)H(5))(C(2)H(3)O)(C(13)H(13)P)(CO)(2)], was prepared by reaction of [Mo(CH(3))(C(5)H(5))(CO)(3)] with methyl-diphenyl-phosphane. The Mo(II) atom exhibits a four-legged piano-stool coordination geometry with the acetyl and phosphane ligands trans to each other. There are several inter-molecular C-H⋯O hydrogen-bonding inter-actions involving carbonyl and acetyl O atoms ...

Biphasic hydroformylation of dec-1-ene and styrene, at commercially competitive rates, can be successfully performed in imidazolium triflate ionic liquids; the ionic liquid network forms 'inclusion complexes' with the phosphane ligands used to modify the rhodium catalyst.
