What is "organotrifluoroborate"

Organotrifluoroborates are organoboron compounds that contain an anion with the general formula [RBF]. They can be thought of as protected boronic acids, or as adducts of carbanions and boron trifluoride. Organotrifluoroborates are tolerant of air and moisture and are easy to handle and purify. They are often used in organic synthesis as alternatives to boronic acids (RB(OH)), boronate esters (RB(OR′)), and organoboranes (RB), particularly for Suzuki-Miyaura coupling.
