New Access to Six-Membered Phosphacycle Annulated Polyaromatic Ring System

A facile Ag-catalyzed intramolecular C–P bond formation reaction from easily accessible phosphine oxides has been developed. Several new heteroatoms fused π-conjugated molecules were synthesized from this procedure with their structures confirmed by X-ray

Topologically diverse polycyclic aromatic hydrocarbons from pericyclic reactions with polyaromatic phospholes

Polycyclic Aromatic Hydrocarbons (PAHs) with planar, twisted and negatively curved topologies were obtained from polycyclic phospholes using pericyclic reactions. Deviation from planarity is due to steric interactions between the PAH core and the ester substituents. These structural effects on the optical and redox properties were studied and rationalized through DFT calculations. This synthetic approach thus allows the preparation of topologically diverse PAHs allowing fine-tuning their electronic properties, with potential applications in organic electronics.

Cyclization of Bisphosphines to Phosphacycles via the Cleavage of Two Carbon-Phosphorus Bonds by Nickel Catalysis

The nickel-catalyzed cyclization of bisphosphine derivatives to form various phosphacycles is reported. The reaction proceeds via the cleavage of two carbon-phosphorus bonds of the bisphosphine. Unlike the previously reported palladium catalysts, the use

Palladium-catalyzed cyclization of bisphosphines to phosphacycles via the cleavage of two carbon-phosphorus bonds

A catalytic method for the synthesis of dibenzophosphole derivatives using bisphosphines as the starting material is developed. The reaction proceeds through the cleavage of two carbonphosphorus bonds of the bisphosphine substrate. The reaction can also be used in the synthesis of six-membered phosphacycles.

Synthesis, crystal structure, dynamic behavior and reactivity of dinaphtho[2,1-b:1',2'-d]phospholes and related atropisomeric phosphacyclic derivatives

7-Phenyldinaphtho[2,1-b:1',2'-d]phosphole (1b) has been prepared by reaction of dichlorophenylphosphine either with 2,2'-dilithio-1,1'-binaphthalene or with bis-dialin 7. In the latter case the relevant tetrahydro derivative 8 is formed at the same time.

Streoselective reaction of (+/-)-7-Phenyldinaphthophosphole with an optically active palladium complex. Molecular structure and fluxional behavior of PdCl

Reaction of (+/-)-7-phenyldinaphthophosphole (1) with one-half equivalent of an optically active palladium complex, (μ-Cl)>2 ((S)-3a), proceeded stereoselectively to give one of the diastereomers, PdCl ((S)(P)-4a), accompanying racemization of 1.The X-ray crystallographic analysis of (S)(P)-4a determined the absolute configuration of the coordinated phosphole unequivocally to be P.The fluxional behavior of 4a and the related complex is also discussed.Key words: Palladium; Phosphine; Fluxionality; Isomerism; Stereoselectivity; X-ray diffraction
