| 摘要 |
The essence of the invention is the use of chiral ionic salts containing a menthoxymethylimidazolium cation and tetrafluoroborate anion as a means of herbicidal properties. In the use according to the invention as ionic salts alkylimidazolium cation and tetrafluoroborate anion is used, preferably 3-[(1 R ,2 S ,5 R -(-)-menthoxymethyl]-1-methylimidazolium tetrafluoroborate, 3-[(1 R ,2 S ,5 R -(-)-menthoxymethyl]-1-propylimidazolium tetrafluoroborate, 1-hexyl-3-[(1 R ,2 S ,5 R -(-)-menthoxymethyl]imidazolium tetrafluoroborate, 3-[(1 R ,2 S ,5 R -(-)-menthoxymethyl]-1-octylimidazolium tetrafluoroborate, 3-[(1 R ,2 S ,5 R -(-)-menthoxymethyl]-1-nonylimidazolium tetrafluoroborate, 1-decyl-3-[(1 R ,2 S ,5 R -(-)-menthoxymethyl]imidazolium tetrafluoroborate, 3-[(1 R ,2 S ,5 R -(-)-menthoxymethyl]-1-undecylimidazolium tetrafluoroborate. |
