Abstract
2,3-Bis(hydroxyimino)-2,3-dihydro-4H-1,4-benzothiazine (BTIH2) has been synthesized from 0-aminothiophenol and cyanogen-di-N-oxide which was obtained by treating anti-dichloroglyoxime with 1N Na2CO3 at - 10°C. The amphi-isomer was prepared by crystallizing the crude product in pyridine/water (1:5). The conversion of the crude product to anti-BTIH2 was accomplished by the effect of HC1 and neutralizing afterwards, anti-BTIH2 formed square planar, H-bridged complexes with Ni(II), Cu(II), and Co(II). The N,0-chelated tetrahedral Ni(II) complex of amphi-BTIH2 was yellow-green. 1H-NMR, IR, and UV-VIS data are presented.Keywords
