A Tf2O-mediated intramolecular phospha-Friedel-Crafts-type reaction of secondary biarylphosphine oxides has been developed. The reaction is promoted simply by Tf2O to form the corresponding dibenzophospholes under metal-free conditio

A palladium-catalyzed intramolecular direct arylation reaction was developed and two efficient one-pot sequential direct arylation/Suzuki-Miyaura coupling and intra/intermolecular direct arylation reations were also realized. The method provides a simple and straightforward procedure for the synthesis and further functionalization of dibenzophosphole oxides from easily accessible ortho-halodiarylphosphine oxides in good to excellent yields.
Palladium-catalyzed direct synthesis of phosphole derivatives from triarylphosphines through cleavage of carbon-hydrogen and carbon-phosphorus bonds

(Phosp)hole in one: A palladium-catalyzed synthesis for directly assembling phosphole skeletons from triarylphosphines through C-H and C-P bond cleavage was developed. This approach overcomes several of the limitations of the so far reported methods. Phospholes bearing a range of functionalities (including Br, F, CO2Me, Ac, and CN) and an array of fused rings (naphthalenes, anthracenes, furans, and pyrroles) can be easily synthesized. Copyright
Palladium-catalyzed synthesis of dibenzophosphole oxides via intramolecular dehydrogenative cyclization
Kuninobu, Yoichiro,Yoshida, Takuya,Takai, Kazuhiko
, p. 7370 - 7376 (2011/11/04)
Dibenzophosphole oxides were obtained from secondary hydrophosphine oxides with a biphenyl group by dehydrogenation via phosphine-hydrogen and carbon-hydrogen bond cleavage in the presence of a catalytic amount of palladium(II) acetate, Pd(OAc)2/sub
