The first electrochemical synthesis of diarylphosphole oxides (DPOs) was achieved under mild conditions. The practical protocol employs commercially available and inexpensive DABCO as a hydrogen atom transfer (HAT) mediator, leading to various DPOs in moderate to good yields. This procedure can also be applied to the synthesis of six-membered phosphacycles, such as phenophosphazine derivatives. Mechanistic studies suggested that the reaction proceeds via an electro-generated phosphinyl radical.

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 of o -bromoaryl phosphine oxides was developed to afford a variety of P-stereogenic phosphole oxides in good yields. The enantioselectivities were closely associated with the specific structures of substrates, which ranged from 4-94%. As a result of ready availability of starting materials and simple operation to improve the enantioselectivities of the products with low ee values, the method provides a simple and straightforward procedure for the synthesis of P-stereogenic phosphole oxides.

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.

(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
