An unprecedented direct atom-economic chemo- and regioselective hydroalkylation of chloroalkynes and an sp3-C,H alkynylation of bromoalkynes was achieved, reaction partners are unfunctionalized ethers, alcohols, amides, and even non-activated hydrocarbons. We found that a household fluorescent bulb was able to excite diaryl ketone, which then selectively abstracts a H atom from an sp3-C-H bond. The product of formal alkyne insertion into the sp3-C-H bond was obtained with chloroalkynes, providing valuable vinyl chlorides. Th
