FIELD: chemistry.
SUBSTANCE: invention relates to organophosphorus chemistry, namely to α-hydroxyphosphonates-racemate of O, O-dialkyl(Z)-(2-bromo-1-hydroxy-3-phenyl-2-propen-1-yl) phosphonates of general formula (I):
R = C2H5 (ethyl) (Ia), R = i-C3H7 (isopropyl) (Ib), R = C4H9 (butyl) (Ic), R = i-C4H9 (isobutyl), (Id), having bactericidal and fungicidal activity.
EFFECT: present invention provides development of new compounds – racemates of O, O-dialkyl(Z)-(2-bromo-1-hydroxy-3-phenyl-2-propen-1-yl) phosphonates, which do not require complex procedures of synthesis and purification, have high bactericidal and fungicidal activity, expanding the range of known agents for said purpose.
