ORGANOPHOSPHORUS COMPOUNDS AS POTENTIAL FUNGICIDES. PART II. AMINOALKANE-, GUANIDINOALKANE-, AND THIOUREIDOALKANE-PHOSPHONIC ACIDS: PREPARATION, SPECTROSCOPY, AND FUNGICIDAL ACTIVITY

A range of α-amino-, ω-amino-, α-guanidino-, and ω-guanidinoalkanephosphonic acids has been prepared for the purpose of studying their spectroscopic features and fungicidal activity.In addition, α-thioureido-octanephosphonic acid and thioureylene-1,1-bis(1-octanephosphonic acid) were isolated during the preparation of α-guanidino-octanephosphonic acid. 31P, 1H, and 13C nmr spectral data which were obtained for solutions of the amino- and guanidino-compounds in D2O or D2O/D2SO4, and for the thioureido compounds in DMSO-d6, are discussed together with previouslyreported data for the aminophosphonic types.FAB mass spectrometry generally gives strong pseudomolecular ions + for the zwitterionic amino- and guanidino-compounds with relatively simple fragmentations.Fungicidal activity of the α-aminophosphonic acids was found to be greater than for the ω-amino compounds, with maximum activity at a chain length of three carbon atoms when used as a seed dressing for the control of Drechslera spp.Moderately good activity was shown by the thioureido compounds against a number of fungal organisms in vitro but the guanidino-compounds exhibited low activity.Key words: Organophosphorus; fungicides; aminophosphonic acids; guanidinophosphonic acids; NMR spectroscopy; FAB mass spectroscopy.
