The aminoazanium of DABCO (H2 N-DABCO) has been developed as a general and practical amination reagent for the direct amination of alkyl and aryl pinacolboronates. This compound is stable and practical for use as a reagent. Various primary, secondary. and tertiary alkyl-Bpin and aryl-Bpin substrates were aminated to give the corresponding amine derivatives. The amination is stereospecific. The anti-Markovnikov
additive-free strategy for the defluorinative alkylation of trifluoromethyl groups is presented. A broad range of polyfluorinated compounds was easily converted into difluoromethyl products. Simple and inactivated alkenes, such as ethylene, were found to be suitable substrates. Furthermore, complex deuterated α,α-difluoromethyl derivatives could be obtained. The mechanism was investigated by combining
