Abstract

A very simple method for the preparation of several active N-chloro compounds that have extensive applications in organic synthesis, industry, and medicine has been developed. Tetrachloroglycolurils, chloramine-T, N-chlorosaccharin, N-chlorosuccinimide, N-chlorophthalimide, N,N′-dichlorophenobarbital, and N,N′-dichlorobarbital were synthesized by chlorination with trichloroisocyanuric acid under mild reaction conditions at room temperature. This method is clean, fast, and efficient; the yields are also good to excellent.

These compounds have been extensively investigated since their discovery by Schiff in 1877. Glycoluril (IUPAC name: perhydroimidazo[4,5-d]imidazole-2,5-dione) and its derivatives are heterocyclic compounds that have found a number of applications, including polymer cross-linking, explosives, stabilizers of organic compounds against photodegradation, and combinatorial chemistry. Glycoluril has also been used as a building block for various supramolecular objects. Among others, the groups of Rebek,³² Nolte,³³ and Isaacs³4 have extensively studied the synthesis and behavior of a wide variety of glycoluril derivatives.
