Formation of oxoborane and thioxoborane from a dithiastannaboretane derivative

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.

Synthesis and structures of novel dithiaboretanes containing a group 4, 14, or 15 element

Dilithiation of the dimercaptoborane TbtB(SH)2 (1), which was synthesized by the sulfurization of the corresponding overcrowded lithium aryltrihydroborate bearing the 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt) group, followed by treatment with electrophiles such as Cp2TiCl2, Mes2GeBr2, Ph2SnCl2, and TbtSbBr2 resulted in the isolation of novel four-membered boracycles, 1,3,2,4-dithiaboratitanetane, 1,3,2,4-dithiagermaboretane, 1,3,2,4-dithiastannaboretane, and 1,3,2,4-dithiastibaboretane as stable crystals, respectively. The introduction of a C, Si, or P atom to the four-membered ring was not successful. The structures of the newly obtained four-membered boracycles were determined by X-ray crystallographic analysis. The four-membered rings are almost planar and perpendicular to the aromatic ring of Tbt group. The geometries around the boron atom in the four-membered ring are found to be almost trigonal planer, and the S-B-S angles in the ring are not much smaller than 90°, indicating that the geometry around the boron and sulfur atoms was not so different from that of 1 in spite of being embedded in the ring system.
