Title:
LABELING METHOD, OXIDANT FOR LABELING, RUTHENIUM COMPLEX, CATALYST, LABELING COMPOUND, AND COMPOUND
Document Type and Number:
WIPO Patent Application WO/2022/138748
Kind Code:
A1
Abstract:
The present invention provides a labeling method that comprises a step for labeling a substrate, which has a carbon-hydrogen bond, with an oxygen isotope with use of a catalyst and an oxidant that is produced from a hypervalent iodine compound having an ester structure and labeled water which is labeled with at least one oxygen isotope that is selected from the group consisting of 17O and 18O. The present invention also provides an oxidant for labeling, said oxidant being produced from a hypervalent iodine compound having an ester structure and labeled water which is labeled with at least one oxygen isotope that is selected from the group consisting of 17O and 18O. This oxidant for labeling labels a substrate, which has a carbon-hydrogen bond, with an oxygen isotope in the coexistence of a catalyst.
