“…the acetyl group. Experimental 3-Acetylamino-l,4-benzoquinone 4-oxime was obtained from the nitrosation of 3-acetylaminophenol in the presence of nickel(H) chloride hexahydrate together with bis(5acetylamino-l,2-benzoquinone 2-oximato)nickel(II) hexahydrate, and was recrystallized from ethyl acetate (Barjesteh, Charalambous & Pathirana, 1993). The methods of data collection and data processing were similar to those described previously (Adams et al, 1980).…”
