An ultrafine Ni2P (a metal-rich interstitial phosphide compound) nanoparticles with a narrow size distribution homogeneously dispersed on N,P-codoped carbon was developed for efficient synthesis of alkynyl thioethers via base- and ligand-free cross-dehydrogenative coupling (CDC) of terminal alkynes and thiols using atmospheric air as the oxidant under mild conditions. A remarkable catalytic performance with good functional group compatibility, broad substrate scope and high stability is accomplished. Pyridinic N atoms are identified as basic sites for facilitating the activation of terminal alkynes via hydrogen bonding interactions and play a key role in the success of this base- and ligand-free CDC reaction.

Nucleophilic addition to thioalkynes was investigated under various catalytic conditions with gold(I) complexes being identified as the optimal catalysts. Structural evaluation of the product revealed an unexpected cis-addition, arising from a gold-associated thioketene intermediate. Based on this interesting mechanistic insight, a gold(I)-catalyzed thioether addition to thioalkynes was developed as a novel approach to prepare ketene dithioacetals with good yields and high efficiency.

An iridium-catalyzed azide-alkyne cycloaddition reaction (IrAAC) of electron-rich internal alkynes is described. It is the first efficient intermolecular AAC of internal thioalkynes. The reaction exhibits remarkable features, such as high efficiency and r

Hydroboration of 1-alkylthio-1-alkynes with dicyclohexylborane or bis(1,2-dimethylpropyl)borane proceeded smoothly, adding most of the dialkylboryl group to the α-position of the triple bond. The resulting alkenylboranes afforded either S-alkyl alkanethio
