The present invention provides compounds comprising propynyl uracils having the formula
wherein R1 is hydrogen, chlorine, bromine, iodine, fluorine, —CN, substituted or unsubstituted linear or branched C1-C4 alkyl, —NO2, methoxy, ethoxy, n-propoxy, or iso-propoxy; R2 is iodine or bromine; and R3 is propynyl, 3-iodopropynyl, 3-bromopropynyl, substituted or unsubstituted 2-furanyl, substituted or unsubstituted 3-furanyl, substituted or unsubstituted 2-pyrrolidinyl, substituted or unsubstituted 3-pyrrolidinyl, D-ribose, or deoxyribose. Another embodiment of the invention encompasses propynyl uracils having the formula
wherein R4 is hydrogen, chlorine, bromine, iodine, fluorine, —CN, substituted or unsubstituted linear or branched C1-C4 alkyl, —NO2, methoxy, ethoxy, n-propoxy, or iso-propoxy; R5 is hydrogen or propynyl; and R6 is iodine or bromine. Also, methods of preparing these propynyl uracils are provided. The propynyl uracils of the present invention are useful as biocides, including, but not limited to, bactericides, fungicides, and preservatives.
