| 摘要 |
The invention provides amidoxime derivatives of the general formula <IMAGE> wherein R1 is an alkyl group of 1 to 8 carbon atoms, phenyl, a heterocyclic ring structure of 5 to 8 atoms containing one or more nitrogen or oxygen atoms or combinations thereof or a bicyclic condensed ring system optionally containing at least one heterocyclic ring which groups may each be optionally substituted. R2 is a mono or bicyclic heterocyclic radical containing at least two nitrogen atoms which radical is also optionally substituted. R3 and R4 are independently H, or an alkyl of 1 to 4 carbon atoms or one, but not both, is <IMAGE> and the other, H, wherein R5 or R6 are alkyls of 2 to 5 carbon atoms optionally substituted by R1, or a phenyl optionally substituted by R1 or R5 or R6 is combined with R1 to jointly form cyclic imidoximes or imidedioximes. The invention also provides processes for the preparation of these compounds and many uses therefor including application in affinity chromatography, enzyme reactors and for preparing dense and porous fibers, fabrics and particles.
