A novel approach was developed to prepare Pd nanoparticles with organic ligands in high yields. The structural unit of the Pd species was constructed involving Pd-S bonds. The synthesized Pd particles were highly selective catalysts of S-H bond addition to alkynes under microwave heating. An X-ray diffraction study of one of the products of the addition reaction revealed unusual supramolecular organization of cation/anion layers.

Vinyl sulfides represent an important class of compounds in organic chemistry and materials science. Atom-economic addition of thiols to the triple bond of alkynes provides an excellent opportunity for environmentally friendly processes. We have found that well-known and readily available Pd-NHC complex (IMes)Pd(acac)Cl is an efficient catalyst for alkyne hydrothiolation. The reported technique provides
