Synthesis and reactivity of amino-substituted BEDT-TTF donors as building blocks for bifunctional materials

The first two amino-substituted BEDT-TTF derivatives, aminomethyl-ET (AMET) and aminoethyl-ET (AEET), have been prepared; the critical step in both cases was a hetero Diels–Alder reaction with 1,3-dithiole-2,4,5-trithione. AEET shows expected reactivity towards electrophiles whereas AMET will not react with aryl acid chlorides or sulfonyl chlorides, but amides of AMET can be produced by DCC coupling and mixed anhydride methods.
