Abstract:
Aryl borates are one of the most important synthetic materials in organic synthesis. Herein, we report a visible-light-induced electron donor-acceptor (EDA)-based borylation protocol between thianthrenium salts and 1,4-diazabicyclo[2.2.2]octane (DABCO) for the synthesis of various aryl boronates without a photocatalyst or stepwise processing. Remarkably, this photochemical strategy is compatible with a wide range of sensitive functional groups and affords excellent yields. Moreover, the quantitative recovery of thianthrene for feedstock synthesis lowers the reaction cost.

Electrophilic Addition to Alkynes: Halogenation
Halogenation is another class of electrophilic addition reactions where a halogen molecule gets added across a π bond. In alkynes, the presence of two π bonds allows for the addition of two equivalents of halogens (bromine or chlorine). The addition of the first halogen molecule forms a trans-dihaloalkene as the major product and the cis isomer as the minor product. Subsequent addition of the second equivalent yields the tetrahalide.
