Cyanuric chloride is the chemical compound with the formula (NCCl)3. This colorless solid is the chlorinated derivative of 1,3,5-triazine. It is the trimer of cyanogen chloride [1].
The compound is employed as a reagent in organic synthesis for the conversion of alcohols and carboxylic acids into alkyl and acyl chlorides, respectively. It is also used as a dehydrating agent and for the activation of carboxylic acids for reduction to alcohols. Heating with DMF gives Gold's reagent Me2NCH=NCH=NMe2+Cl-, which is a versatile source of aminoalkylations and a precursor to heterocycles.[2]
The chlorine atoms are easily replaced by amines to a melamine for example in the the synthesis of this first generation dendrimer [3] [4]:
or in the synthesis of an experimental adenosine receptor ligand [5]:
