  • A General Synthesis of Diaryl Cyclic Diamidines
    Publication

    A convenient and general method has been developed for directly converting bis-nitriles, e.g., I, to cyclic diamidines, e.g., II, using reagents derived from diaminoalkanes, e.g., H2NCH2CH2NH2, satd. with hydrogen sulfide. A 1:1 mixt. of a diaminoalkane and Et alc. (or without) was effective in most cases (72-88%). The synthetic utility of this methodol. in the prepn. of tetrakis(cyclic amidino)pyrenes III (R = H, Me) from 1,3,6,8-tetracyanopyrene...
