Abstract

The key photocatalytic properties of a transition-metal-free heteroleptic complex derived from 1,4-phenyldiboronic acid were evaluated. This compound was utilized in the atom transfer radical addition of iodoperfluoroalkanes to a series of alkenyl group bearing organoboron compounds. The products of these reactions retained the BC bond, and Suzuki-Miyaura coupling of one product gave biphenyl derivatives. The X-ray analysis of one of the obtained perfluoroalkylated boronic acids revealed the presence of open star-shaped channels.
