A metal-free route for the synthesis of biarenes has been developed. The approach is based on the photoextrusion of a phosphate moiety occurring upon irradiation of biaryl- A nd triaryl phosphates. The reaction involves an exciplex as the intermediate and it is especially suitable for the preparation of electron-rich biarenes.

Copper-catalyzed aerobic oxidative esterification of P(O)-OH compounds is achieved using alcohols as efficient esterification reagents, giving the expected products with good to moderate yields. Furthermore, it is shown that the arylation of P(O)-OH compounds proceeds efficiently to produce the corresponding products via the treatment of diaryliodonium triflates under mild reaction conditions. It is a simple way to produce a broad spectrum of functionalized phosphinates, phosphonates, and phosphates from basic starting materials with good to excellent yields. The protocol is convenient for practical application. A plausible mechanism has been proposed for the reaction.
A simple and effective method for phosphoryl transfer using TiCl4 catalysis
Jones, Simon,Selitsianos, Dimitrios
, p. 3671 - 3673 (2007/10/03)
(graph presented) A number of Lewis acids have been evaluated as catalysts for the phosphoryl transfer, the most efficient being TiCl4. Application of this methodology to the phosphorylation of a number of representative target alcohols is presented.
