Cyclometallated gold(iii) hydroxides as versatile synthons for Au–N, Au–C complexes and luminescent compounds†
Abstract
The gold(III) hydroxide κ3-(C∧N∧C)*Au(OH) reacts with C–H and N–H compounds and arylboronic acids to produce a range of perfluoroaryls, N-heterocyclic and alkynyl compounds in high yields; some of which show unexpectedly strong modulation of their photoluminescence from yellow to blue [(C∧N∧C)* = 2,6-(C6H3But)2pyridine].
