Xu, Zi-Yang published the artcilePhotocatalytic Chemodivergent Synthesis of α-gem-Dihalovinyl Ketones and Chromen-2-Ones from Monoalkynes, Formula: C7H11Br, the publication is Advanced Synthesis & Catalysis (2022), 364(15), 2666-2672, database is CAplus.
A general photocatalytic substrate-controlled chemodivergent strategy starting from monoalkynes with polyhalomethanes such as BrCCl3 and CBr4 was developed, enabling Kharasch-type addition/nucleophilic substitution cascade to selectively produce α-gem-dihalovinyl ketones and chromen-2-ones with moderate to good yields. Use of monoalkynes without addnl. nucleophilic sites furnished α-gem-dihalovinyl ketones through a Kharasch-type addition and intermol. allylic substitution cascade whereas the latter transformation of 2-ethynylphenols allowed the full breaking of carbon-halogen bonds of BrCX3 to access functionalized chromen-2-ones. The late-stage application of these resulting α-gem-dihalovinyl ketones demonstrates the versatility of their derivatization.
