Abstract
A catalytic method to synthesize a diverse array of phosphorus-bridged biaryls from readily available tertiary phosphines is described by K. Baba, M. Tobisu, and N. Chatani in their Communication on page 11892 ff. The substrate must surmount two barriers, namely the cleavage of CH and CP bonds, to be transformed into the product. This process is facilitated by a palladium catalyst to afford various phosphorus-based π systems, some of which exhibit intense solid-state fluorescence.
