The invention discloses a method for preparing aryl vinyl alkyl thioether through a C = C-S monatomic assembly process, which comprises the following steps: respectively providing an atom for a C = C-S structure by dimethyl sulfoxide, aromatic aldehyde ketone and sulfur-containing reagent sodium mercaptide/dithioether under the action of air atmosphere and alkali; the construction process is completed by one-pot reaction, and the product aryl vinyl alkyl thioether compound is obtained. The aryl vinyl of the aryl vinyl alkyl thioether compound prepared by the method comes from aromatic aldehyde ketone, but a double-bond carbon atom is added compared with the original aromatic aldehyde ketone raw material, and the method has the advantages of wide and easily available raw material source, environmental protection, low price, simple operation and facilitation of industrial production.

The catalytic activity of a set of mono- and bimetallic Rh(i) and Ir(i) complexes bearing carbene-linker-carbene (CXC) bis-triazolylidene ligands (with X = O, N) coordinated in a bridging or chelating fashion was evaluated in the hydrothiolation of alkyne

The sulfur oxygen (S?O) interaction was used herein to obtain (Z)-selectiveanti-Markovnikov vinyl sulfides from the addition of thiyl radicals to terminal alkynes. DFT calculations predicted that S?O interaction originated from the delocalization of the lone-pair of the carbonyl oxygen to the adjacent σ* orbital of the S atom of C-S.
