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.
