A secondary phosphine oxide (SPO)-nickel catalyst allowed the activation of otherwise inert C–F bonds of unactivated arenes in terms of challenging couplings with primary and secondary alkyl Grignard reagents. The C–F activation is characterized by mild reaction conditions and high levels of branched selectivity. Electron-rich and electron-deficient arenes were suitable electrophiles for this transformation
In general, the invention relates to compounds useful as ion channel modulators. It has now been found that compounds of this invention, and pharmaceutically acceptable compositions thereof, are useful as inhibitors of voltage-gated sodium channels and/or calcium channels.

This invention is in the field of medicinal chemistry. In particular, the invention relates to a new class of small-molecules having a quinazolinedione structure which function as reactive oxygen species (ROS) inducers and inhibitors of mitochondrial activity within cancer cells (e.g., pancreatic cancer cells), and their use as therapeutics for the treatment of cancer (e.g., pancreatic cancer) and other diseases.
