  A novel approach to an oxoborane and its Lewis base complex

  摘要：

  Reaction of dimethyl sulfoxide (DMSO) with 1,3,2,4-dithiastannaboretane 3 bearing an extremely bulky aryl group, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt), an the baron atom gave an oxoborane (Tbt-B=O; 4), which formed a complex with DMSO stable in solution. The formation of the complex was confirmed by B-11 NMR and a [3+2] cycloaddition reaction with 2,4,6-tri-t-butylbenzonitrile oxide. (C) 1997 Elsevier Science Ltd.

  Formation of Oxoborane and Thioxoborane from a Dithiastannaboretane Derivative

  摘要：

  Reaction with an oxygen-donating reagent such as DMSO and thermolysis of a 1,3,2,4-dithiastannaboretane derivative bearing 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt) group led to the formation of novel boron-group 16 element double bond compounds, oxoborane (Tbt-B=O) and thioxoborane (Tbt-B=S). The oxoborane and thioxoborane underwent cycloaddition reactions to give the corresponding adducts in good yields.
