Boronic compound complexing reagents and highly stable complexes

(57) The synthetic method of the middle reagents of a summary boron 化合物錯-ized reagent and the above-mentioned reagent and these reagents is indicated. If these reagents containing what shown are used as the general formula 1 and the general formula II, it can 錯-ize with boron compounds, such as phenylboronic acid or its derivative, after the addition reaction written in this specification. The synthetic method of of a boron 化合物錯-ized reagent, boron compound complexes, and these reagents and complexes is indicated. These reagents and complexes contain what is shown in the general formula CIII, the general formula CIV, and the general formula CVI. In one mode, if the reagent of the general formula CIII is used, the reagent of the general formula CIV can be manufactured after a biological activity kind (BAS) and condensation. If the reagent of the general formula CIV is used, a complex with boron compounds, such as a complex shown in the general formula CVI, can be formed.
