| Abstract: | Bis-(trimethylsilyl)acetamide (BSA) reacts with borazines RNBX]3, R=H,X=F; R=CH3,X=F; R=C6H5,X=F and R=C6H5,X=Cl to the corresponding borazines,X=OSi(CH3)3. The1H-NMR signal of the Si(CH)3-groups of C6H5NBOSi(CH3)3]3 is at abnormally high field. With CH3NBCl]3,BSA forms borazines which contain both Si(CH3)3O- and O?C(CH3)=NSiR3 groups bonded to the boron atoms. With LiNSi(CH3)3]2, CH3NBCl]3 forms silylaminoboranes.1H-NMR, mass spectrometric and analytical data are reported. |
