Gold carbonyl cations and beyond: homoleptic gold(i) complexes with P₄ and P₄S₃ and the half-sandwich cation [Au(C₆H₆)(CO)]⁺

Abstract

Oxidation of Au0 with the synergistic Ag+/0.5 I2 system in the commercial organic solvent 1,2,3,4-tetrafluorobenzene led to the per¬fluoro¬alkoxyaluminate salt of the [Au(CO)2]+ cation known from superacid chemistry. This [Au(CO)2]+...
