| 摘要 |
The present invention provides compounds having the formulawherein R1, R2, R3, R4, and R5 are independently hydrogen, chlorine, bromine, fluorine, iodine, substituted or unsubstituted linear or branched C1-C3 alkoxy, substituted or unsubstituted linear or branched C1-C3 thioalkoxy, substituted or unsubstituted linear or branched C1-C8, alkyl, hydroxyl, thiol, -CN, -CF3, -OCF3, -NO2, acetyl, or -NR6R7; R6 and R7 are independently hydrogen, methyl, or ethyl; and X is iodine or bromine. Another embodiment of the invention includes specific ethynyl benzene sulfone derivatives. The alkynyl aryl sulfones of the present invention are useful as biocides, including, but not limited to, bactericides, fungicides, and preservatives. Also, a method of preparing the halogenated alkynyl aryl sulfones of formula I is provided. The method comprises contacting an alkynyl aryl sulfone with N-iodosuccinamide or N-bromosuccinamide, acetone, and silver nitrate to form the corresponding halogenated alkynyl aryl sulfone. |
