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

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.

Palladium-Catalyzed Synthesis of Six-Membered Benzofuzed Phosphacycles via Carbon-Phosphorus Bond Cleavage

The palladium-catalyzed synthesis of dibenzofused six-membered phosphacycles via carbon-phosphorus bond cleavage is developed. This method is compatible with a range of functional groups, such as esters, amides, and carbamates, which is in sharp contrast to the limitations of the classical method using organolithium reagents.

Experimental and quantum chemical studies of 2-phosphinylphenol derivatives

Carbon-oxygen bonds ortho to a phosphoryl group in triarylphosphine oxides undergo cleavage when the oxides are either fused with potassium hydroxide or treated with potassium tert-butoxide in refluxing toluene, presumably through a nucleophilic addition-elimination mechanism. Thus, bis(2-hydroxyphenyl)phenylphosphine oxide is produced along with the expected 2-phenoxyphenyl(phenyl)phosphinic acid from 10-phenyl-10H-phenoxaphosphine 10-oxide. The latter starting material is also produced, together with bis(2-hydroxyphenyl)phenylphosphine oxide, when bis(2-methoxyphenyl)phenylphosphine oxide is fused with potassium hydroxide. Fusion of bis(2-methoxyphenyl)phenylphosphine oxide with sodium hydroxide, however, yields 2-hydroxyphenyl(phenyl)phosphinic acid. Ab initio quantum chemical studies confirm that the downfield 31P chemical shift that is observed in 2-phosphinylphenols is due to hydrogen bonding to the phosphoryl group.
