Literature References

Widely used as a radical trap to inhibit polymerization and peroxidation reactions. Forms inclusion compounds (clathrates) with three molecules of hydroquinone held together by H bonds to form a cage in which a single guest molecule can be accommodated. For a review, see: D. D. MacNicol in Inclusion Compounds, Vol. 2, J. L. Atwood et al, Eds., Academic Press, London (1984), p1. A stable 1:1 complex with hydrazine has been isolated and found to be a useful, safer replacement for anhydrous hydrazine, e.g. in the solid state reaction with esters to give hydrazides: J. Chem. Soc., Chem. Commun., 1531 (1995).
