		In organizing this multi-authored volume, I felt it would be most appropriate that the first four chapters deal with recent developments involving the well established, older, reagents (such as elemental fluorine, interhalogen monofluorides, hypervalent halogen mono-fluorides, and xenon difluoride).
		The ensuing nine chapters delineate/describe/outline the progress in synthetic fluorination chemistry involving the more recently developed electrophilic and nucleophilic reagents (such as N-fluoropyridinium, onium polyhydrogen fluorides, Selecfluor, the chiral NF compounds, DAST and Deoxofluor), while the last three chapters focus on enzymatic synthesis and the organometallic/heteroatom chemistry aspects.

		Thus, when chlorine, bromine, or iodine is bonded to oxygen, the halogen will have an oxidation number higher than 0.
		Furthermore, in an interhalogen compound the halogen with the higher atomic number should be given the higher oxidation number.
		First, when oxygen atoms in a compound are joined by an -O-O- bond the oxidation number of oxygen is -1.
