First ever observation of the intermediate of phosphonium salt and ylide hydrolysis: P-hydroxytetraorganophosphorane

P-Hydroxytetraorganophosphorane, the long-postulated intermediate in phosphonium salt and ylide hydrolysis, has been observed and characterised by low temperature NMR, finally definitively establishing its involvement in these reactions. The results require modification of the previously accepted mechanism for ylide hydrolysis: P-hydroxytetraorganophosphorane is generated directly by 4-centre reaction of ylide with water.

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.

Electrosynthesis of Phosphacycles via Dehydrogenative C-P Bond Formation Using DABCO as a Mediator

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.
