Design and Synthesis of Polytopic Metalloligands Based on Fluoroaryl Gold(I) Organometallic Compounds
New neutral and anionic fluoroaryl gold(I) complexes featuring terminal pyridine rings were prepared following different strategies. The homoleptic anionic compounds NBu4[Au(C5F4N)2] (1) and NBu4[Au(C6F4py)2] (2) were obtained by reacting [AuCl(tht)] (tht = tetrahydrothiophene) with the organolithium derivatives of BrC5F4N and BrC6F4py, respectively. This route required the previous synthesis of the
