Abstract
The novel 1,4-dithia-2,6-diaza-3,5-diborinane ring system results from the reaction of 3,5- dialkyl- (or di-sec.amino-) substituted 1,2,4-trithia-3,5-diborolanes with 1.3-disubstituted sulfurdiimides by replacement of the disulfane bridge. Upon treatment with azomethines, 3,5-dibromo- 1.2.4-trithia-3,5-diborolane gives 3,5-dibromo-1,2-dithia-4-aza-5-diborolidines by substitution of the sulfur atom in position 4. 1H , 11B , 13C, 29Si NMR and mass spectra are reported and discussed.
