摘要：

A series of amine-alkyl[(ethylimino)alkoxymethyl]boranes (alkyl = i-Pr, i-Bu, s-Bu, and benzyl; alkoxy = MeO, EtO, and benzyl-O) were synthesized by two different methods. The first method consisted of reacting an (amine-alkyl(N-ethylcarbamoyl)borane with an excess of Et3OBF4 in CH2Cl2, followed by deprotonation of the resulting amine-alkyl[(ethyliminiumylidene)ethoxymethyl]borane tetrafluoroborate with aqueous sodium hydroxide. In one case the intermediate amine-alkyl[(ethyliminiumylidene)alkoxymethyl]borane tetrafluoroborate was stable enough to be fully characterized. The second more direct method involved reacting an amine-alkyl[(ethylnitrilio)methyl]borane tetrafluoroborate with a sodium alkoxide in alcohol.
