• W2611681946 abstract "A C,S-cycloaurated complex based on an ortho-substituted phosphinothioic amide framework has been synthesized in high yield through tin(IV)–Au(III) transmetalation from the corresponding chlorodimethylstannyl derivative. The latter was prepared in a two-step process involving directed ortho lithiation/quenching with Me3SnCl followed by Me/Cl exchange. The tin(IV) and gold(III) complexes have been characterized in solution and in the solid state. In both complexes, the phosphinothioic amide moiety acts as a C–C–P–S pincer ligand with formation of five-membered-ring metalacycles. The use of the gold(III) complex in the amine–aldehyde–alkyne (A3) three-component coupling synthesis of propargylamines showed that the compound is transformed into the Sonogashira-type o-alkynylphosphinothioic amide with generation of Au(I) nanoparticles with an average size of around 7 nm. These nanoparticles proved to be excellent catalysts in A3 coupling processes, providing propargylamines in high yields under solvent-free conditions with loadings as low as 0.1 mol % and without the use of additives." @default.
