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 preparation of several vinyl sulfides, selenides and tellurides by Wittig-type reaction in a one-pot procedure is described. The chalcogenyl triphenylphosphoranes 3 are formed 'in situ' by the reaction of chloromethyl phenyl chalcogenide, potassium tert-butoxide and triphenylphosphine. Reaction of 3 with carbonyl compounds affords the vinyl chalcogenides 6-9 with preferential Z-configuration.
