摘要：

Computational comparison of the [2+2] and [4+2] reactions between aminoboranes R2B=NR'(2) and alkenes CH2=CH(R") shows that the latter are strongly preferred. The preference arises from the [4+2] reactions exhibiting lower reaction barriers than do the [2+2] reactions; the products formed are of nearly equal stability. This behavior mimics that of reactions between alkenes and supports viewing aminoboranes, particularly (F3C)(2)B= NMe2, as acting like polar alkenes.
