C(sp3)–H bonds has been developed. After C–H abstraction by the photo-excited benzophenone, a two-carbon unit was efficiently transferred to the generated radical from 1-tosyl-2-(trimethylsilyl)acetylene to afford the alkynylated product. The present reaction enables construction of various tri- and tetra-substituted carbons from heteroatom-substituted methylenes, methines and alkanes in a highly chemoselective
