Reactions of tris(trimethylsilyl)amine, N(SiMe3)3, with several monochloroboranes, CH3NCH2CH2N(CH3)BCl, o-OC6H4OBCl, and SCH2CH2SBCl, have been examined, and the ((trimethylsilyl)amino)boranes o-OC6H4OBN(SiMe3)2, [o-OC6H4OB]2NSiMe3, SCH2CH2SBN(SiMe3)2, and [SCH2CH2SB]2NSiMe3 have been prepared and characterized by spectroscopic methods. The molecular structure of [o-OC6H4OB]2NSiMe3 has been determined by single-crystal X-ray diffraction analysis and found to crystallize in the orthorhombic space group P212121 (No. 19) with a = 7.189 (1) ?, b = 19.387 (4) ?, c = 24.508 (4) ?, Z = 8, V= 3416 (1) ?3, and ρcalcd = 1.26 g cm-3. The structure was solved by direct methods, and blocked least-squares refinement converged with RF = 10.1% and RwF = 9.2% on 3012 unique data with F > 2σ(F). The structure contains two independent molecules in the unit cell, and the central nitrogen atoms have a trigonal-planar geometry. Important bond distances include B-Nav = 1,421 (13) ?, Si-Nav = 1.783 (7) ?, and B-Oav = 1.390 (13) ?. Attempts to prepare the 1,3,2-diazaborolidine CH3NCH2CH2N(CH3)BN(SiMe 3)2 and triborylamine compounds by this synthetic method were unsuccessful.
