supporting information, p. 3015 - 3020 (2021/05/05)
Chlorination with chlorine is straightforward, highly reactive, and versatile, but it has significant limitations. In this Letter, we introduce a protocol that could combine the efficiency of electrochemical transformation and the high reactivity of chlorine. By utilizing Cl3CCN as the chloride source, donating up to all three chloride atom, the reaction could generate and consume the chlorine in situ on demand to achieve the chlorination of aromatic compounds and electrodeficient alkenes.

Paragraph 0074-0077, (2020/06/30)
The invention relates to a preparation method of a dichloro addition product of aromatic olefin under visible light catalysis. The preparation method comprises the following step: by taking aromatic olefin as a substrate and copper chloride with visible light absorption capability as a chlorine source, reacting in an organic solvent under the irradiation of visible light in an inert atmosphere toobtain a dichloro addition product of the aromatic olefin after the reaction is completed. The aromatic olefin comprises a carbon-carbon double bond and an aryl group connected with the carbon-carbondouble bond through a covalent bond. Visible light is used for providing energy required by the reaction, copper chloride with visible light absorption capacity and a reaction substrate are used for photoinduction of chlorine atom transfer and initiation of an addition reaction to obtain a dichloro addition product, and the method is mild in reaction condition, simple and convenient to operate andwide in universality of the reaction substrate.

A mild and efficient protocol for the preparation of 1,2-dichloroalkane derivatives from olefins using NH4Cl and Oxone at room temperature is described. A variety of terminal, internal, and cyclic alkenes reacted smoothly to give the corresponding dichlorinated products in good to excellent yields. Moreover, 1,2-disubstituted symmetrical and unsymmetrical olefins dichlorinated with moderate to excellent diastereoselectivity. This method precludes the use of acidic additives and transition metals in the synthesis of vicinal dichlorides.
