2-amino heterocycles (1-5) containing the amino group as an element of a partial amidine structure reacted with trichloroacetyl chloride and then with primary arylamines to yield the title compounds (11-26) through the ring closure of isolable N-heteroaryltrichloroacetamide intermediates (6-10).Some of the intermediates were also prepared through an alternative pathway involving trichloracetylphenoxyiminocarbonic chloride.Three of the compounds (12, 18 and 21) displayed the in vitro fungitoxicity equivalent to that of a commercial fungicide mancozeb against A. niger and F. oxysporium at 1000 ppm concentration.Key words: fungitoxic imidazo-1,3,4-oxa-(thia)diazoles, imidazothiazoles, amino groups, the in vitro fungitoxicity
