Potassium peroxymonosulphate → HCID 19900807, compound

Participants

Reaction Steps

A solution of potassium peroxymonosulphate (`Oxone`, trade mark; 12.8 g, 20.8 mmol) in water (52 ml) was added in one portion to a stirred solution of the nitromethylthio derivative (C) (3.64 g, 14.1 mmol) in 1,2-dimethoxyethane (75 ml). The mixture was stirred vigorously for 18 hours. The reaction mixture was diluted with water (300 ml). The solid obtained was collected by filtration, air dried and recrystallised from toluene to give 4-(nitromethylsulphinyl)dibenzofuran as a white solid (3.82 g), m.p. 174°-176° C.; microanalysis found: C,56.8; H,3.2; N,5.0%; C13H9NO4S requires: C,56.7; H,3.3 N,5.1%.
