Carbonyl difluoride boiling point

The high boiling point of trifluoro(phenyl)-/l4-sulfane (4) enables reactions to be performed at atmospheric pressure in normal glassware. It is important that all reactions are carried out under anhydrous conditions and contact with glass be kept to a maximum of several hours to avoid hydrolysis (caution hydrolysis will liberate hydrogen fluoride). It has been reported that trifluoro(phenyl)-24-sulfane can convert carbonyl compounds to gem-difluorides, e.g. 5-6.
