Synthesis of some Important Heterocyclic Compounds via CT Interactions

Synthesis of new heterocyclic compounds by using linear compounds as electron donors and some π-deficient compounds. The four compounds used as electron donors are: 1-acetylthiosemicarbazide; 1-benzoyl-thiosemicarbazide; 1-(4-hydroxyphenyl)thiosemicarbazide; 1-(4-bromo-phenylaceto)thiosemicarbazide. The π-deficient compounds used are: ethenetetracarbonitrile TCNE; (13-dioxo-23-dihydro-1H-inden-2-ylidene)propanedinitrile CNIND; 3-(dicyano-methylene)-2-indolone; 7788-tetracyanoquinodimethane TCNQ; 23-dichloro-56-dicyano-14-benzoquinone DDQ; 2356-tetrachloro-14-benzoqinone CHL; 23-dichloro-14-naphthoquinone DCHNQ; 23-dicyano-14-naphthoqinone DCNQ.
