Asymmetric alkyldifluoroboranes and their use in secondary amine synthesis
Matteson, Donald S.,Kim, Gyung Youn
, p. 2153 - 2155 (2002)
(matrix presented) Asymmetric diol boronic esters with potassium bifluoride form the corresponding alkyltrifluoroborate and free diol under mild conditions. Defluoridation with tetrachlorosilane produces an alkyldifluoroborane intermediate. This conversio
