Stable (sila)difluoromethylboranes via C–F activation of fluoroform derivatives

Abstract

Lithium 1,3-bis(2,6-diisopropylphenyl)-2,3-dihydro-1H-1,3,2-diazaborol-2-uide activates the C–F linkage of fluoroform (CF₃H) and the Ruppert–Prakash reagent (CF₃SiMe₃) to provide difluoromethyl-substituted boranes as air-stable compounds.
