Dimethylaminobis(trifluoromethyl)borane, (CF3)2BNMe2 (A), reacts with epoxides of the general formula to yield five-membered heterocycles , R = Me (1), CH2F (2), CF3 (3), Et (4), Bz (5).With R = Ph a 1:2 mixture of the isomers (6a) and (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 charactrized by elemental analyses, multinuclear NMR, IR and mass spectra. Key words: Oxa-azonia-boratacyclopentanes; dimethylaminobis(trifluoromethyl)borane.
