Exploring Stibanyl Ligand for Accessing Arsinidene and Arsaketene Adducts, and Phosphaketene
The salt metathesis reaction involving a diamine-based antimony chloride precursor with sodium arsaethynolate in the presence of PMe<sub>3</sub> leads to the formation of stibanyl-functionalized PMe<sub>3</sub>-arsinidene (<b>2</b>). Detailed analyses through single-crystal X-ray diffraction and density functional theory of <b>2</b> confirm the presence of covalent Sb-As bonds and reveal its polarized nature with a multiple-bond character. In contrast to the formation of complex <b>2</b>, substituting PMe<sub>3</sub> with xylyl isocyanide or 1,3-diisopropyl-4,5-dimethyl-imidazolin-2-ylidene (<b>I</b><i>i</i><b>Pr</b>) produces an isocyanide-arsinidene adduct (<b>3</b>) and an <b>I</b><i>i</i><b>Pr</b>-arsaketene complex (<b>4</b>), respectively. Furthermore, the related reactions of precursor <b>1</b> with sodium phosphaethynolate yield both a stibanyl-phosphaketene (<b>5</b>) and a stibanyl-functionalized <b>I</b><i>i</i><b>Pr</b>-phosphaketene adduct (<b>6</b>).
