Abstract

A series of silylamines (aminosilanes) have been converted into their borane adducts using (tetrahydrofuran)- or (dimethyl sulfide)-borane as the BH₃ source. Most of the adducts are unstable in solution and undergo rapid Si-N cleavage to give silanes and aminoboranes. Together with Me₃SiNMe₂-BH₃ the complexes with aziridinyl- and azetidinylsilanes are the most stable. A crystal structure investigation of Ph₃Si- N(CH₂)₂-BH₃ has shown that the molecular geometry of the silylamine component of the adduct is virtually identical with that of the free silylaziridine with its steeply pyramidal configuration at nitrogen.
