An efficient method for the preparation of 2,2-diarylvinyl halides from the corresponding 1,1-diarylethylenes has been developed. N-Halosuccinimides (N-bromosuccinimide or N-chlorosuccinimide) were used as the halogenation reagents. The practicability of this method is highlighted by its simple operation, broad substrate scope and capability for large-scale reaction.

Paragraph 0062-0065, (2019/11/28)
The invention belongs to the field of organic selenium chemistry, and particularly relates to a method for synthesizing an alpha,beta-unsaturated selenium compound. The compound is synthesized by using an aryl boronic acid compound, elemental selenium and a diarylethene compound as reaction substrates. The method avoids toxic selenium-mercury reagents and toxic selenide reagents, conforms to the modern green development concept, and provides a green and economical method for synthesizing unsaturated selenium compounds in the future.
Olefin-assisted iron-catalyzed alkylation of aryl chlorides

, p. 2197 - 2202 (2013/10/01)
A selective and operationally simple ironcatalyzed cross-coupling of aryl chlorides with alkylmagnesium halides has been developed. The reaction tolerates various functional groups and exhibits high chemoselectivity even in the presence of aryl bromides. Mechanistic studies indicate the essential role of the olefin substituent for substrate activation. Competing polymerization and reduction are effectively suppressed.
