Chelation-assisted C–C bond activation of biphenylene by gold(<scp>i</scp>) halides


Beucher, Hélène; Schörgenhumer, Johannes; Merino, Estíbaliz; Nevado, Cristina (2021). Chelation-assisted C–C bond activation of biphenylene by gold(<scp>i</scp>) halides. Chemical Science, 12(45):15084-15089.

Abstract

A chelation-assisted oxidative addition of gold(i) into the C-C bond of biphenylene is reported here. The presence of a coordinating group (pyridine, phosphine) in the biphenylene unit enabled the use of readily available gold(i) halide precursors providing a new, straightforward entry towards cyclometalated (N^C^C)- and (P^C)-gold(iii) complexes. Our study, combining spectroscopic and crystallographic data with DFT calculations, showcases the importance of neighboring, weakly coordinating groups towards the successful activation of strained C-C bonds by gold.
