N-heterocyclic carbene stabilized phosphaalkenyl(chloro)stannylene†
Abstract
The new phosphaalkenyl(chloro)tin(II) compound NHC–Sn(Cl)[C(SiMe3)PMes*] was isolated and fully characterized including molecular structure determination by a single crystal X-ray diffraction analysis. Its reaction with Me2SAuCl led to the formation of an unprecedented PC-bridged trinuclear gold complex [AuC(SiMe3)PMes*]3 through the transfer of the phosphaalkenyl substituent to the gold atom.
