Organotrifluoroborates are organoboron compounds that contain an anion with the general formula [RBF3]−.
Organotrifluoroborates are tolerant of air and moisture[1] and are easy to handle and purify.
[3][4] Boronic acids RB(OH)2 react with potassium bifluoride K[HF2] to form trifluoroborate salts K[RBF3].
Organotrifluoroborates are strong nucleophiles and react with electrophiles without transition-metal catalysts.
[6] The mechanism of organotrifluoroborate-based Suzuki-Miyaura coupling reactions has recently been investigated in detail.
