Abstract

5-(N-Bromo) iminothianthrene (2) and 5-(N-bromo) iminothianthrene 10-oxide (5) and 10, 10- dioxide (8) were prepared and their alkaline hydrolyses were studied. The compound 2 and cis-5-(N-bromo) iminothianthrene 10-oxide (cis-5) afforded the corresponding sulfoximine exclusively. While, unexpectedly, both trans-5-(N-bromo) iminothianthrene 10-oxide (trans- 5) and 8 afforded mainly de-brominated products, trans-5-iminothianthrene 10-oxide ( ...
