Abstract
This invention relates to 1,3-cyclohexanedione derivatives and 1,3-cyclopentanedione derivatives that have buffering function in non-aqueous solutions and to the use thereof for tuning the conditions to control chemical events in non-aqueous solutions. One aspect of the invention is a method for buffering a non-aqueous solution, including adding a buffering molecule to the non-aqueous solution, in which the non-aqueous solution contains an organic solvent, the buffering molecule is a 1,3-cyclohexanedione derivative or a 1,3-cyclopentanedione derivative, and the buffering molecule is optionally conjugated to a solid support.
Claims9
In a method of buffering a non-aqueous solution comprising an organic solvent comprising adding a buffering molecule, the improvement wherein said buffering molecule is a compound presented by Formula I:
- wherein R1 to R5 each are hydrogen or a substituent, and any two groups of R1 to R5 optionally form a ring, or Formula II:
- wherein R1 to R3 each are hydrogen or a substituent, and any two groups of R1 to R3 optionally form a ring.
A method for controlling structural change of a compound in a non-aqueous solution, wherein an acid or a base is capable of causing structural change of the compound, and
- the method comprises preparing a non-aqueous solution comprising the compound and a buffering molecule represented by Formula I:
- wherein R1 to R5 each are hydrogen or a substituent, and any two groups of R1 to R5 optionally form a ring, or Formula II:
- wherein R1 to R3 each are hydrogen or a substituent, and any two groups of R1 to R3 optionally form a ring.
