Abstract
Dimethylaminobis(trifluoromethyl)borane, (CF3)2BNMe2 (A), reacts with epoxides of the general formula
to yield five-membered heterocycles
(CF3)2
, R = Me (1), CH,F (2), CF3 (3), Et (4), Bz (5). With R = Ph a 1:2 mixture of the isomers (CF3)2
O (6a) and (CF3)2
(6b) is obtained. To the contrary,
and A form the borane-dimethylamine adduct (H2C=CMe—CH2-O)(CF3)2B • NHMe2 (7). The compounds have been characterized by elemental analyses, multinuclear NMR, IR and mass spectra.
