Abstract

The reaction of 3-chloro-5-methoxy-4H-1,2,6-thiadiazin-4-one (9) with Na2S·9H2O (0.5 equiv) in tetrahydrofuran (THF) at ca. 20 °C for 20 h gives 5,5′-thiobis(3-methoxy-4H-1,2,6-thiadiazin-4-one) (10) in a 44% yield as yellow needles. The compound was fully characterized.

Highlights

  • 1,2,6-thiadiazines could act as isosters to other 6-membered hetarenes; the formation of a th1i,o2,a6m-thidiaedoinaztointehsectohuialddiaacztinaes cisoousltderosffteoroathneerw6-smcaeffmoblderfeodr thheetasryenntehse;stihseorfefboiroelo, tghiceaflolyrmacattiivoen mofoaletchuiloeasm

  • The UV-vis spectrum was obtained using a Perkin-Elmer Lambda-25 UV-vis spectrophotometer (Perkin-Elmer, Waltham, MA, USA) and inflections are identified by the abbreviation “inf”

  • The IR spectrum was recorded on a Shimadzu FTIR-NIR Prestige-21 spectrometer (Shimadzu, Kyoto, Japan) with the Pike Miracle Ge ATR accessory (Pike Miracle, Madison, WI, USA) and strong, medium and weak peaks are represented by s, m and w, respectively. 1H and 13C NMR spectra were recorded on a Bruker Avance 500 machine (at 500 and 125 MHz, respectively (Bruker, Billerica, MA, USA))
