Title:
NITROAROMATIC SOLUBILIZER FOR NITROXYLS IN AROMATIC SOLVENTS
Document Type and Number:
WIPO Patent Application WO2001083567
Kind Code:
A3
Abstract:
Disclosed herein is a method for increasing the solubility of a compound having the structural formula (I), in an aromatic hydrocarbon solvent comprising adding to said solvent a nitroaromatic compound having the structure (II) wherein, in formula (II), R25, R26, R27, R28, R29 and R30 are independently selected from the group consisting of hydrogen, alkyl, aryl, cycloalkyl, heterocyclic, substituted alkyl, substituted aryl, OR11, NR11R12, SR11, NO2, NO, CN, COR11, COOR11, CONR11R12, NR11COR12, halogen, and/or any two adjacent groups can be taken together to form ring structures(s) of five to seven members, provided that at least one of R25, R26, R27, R28, R29 and R30 is NO2, and R11 and R12 are independently selected from the group consisting of hydrogen, alkyl, aryl, benzyl, cyclic, heterocyclic, and substituted alkyl or aryl where the substituents are C, O, N, S, or P, or R11 and R12 can be taken together to form a ring structure of five to seven members and, in formula (I), R1 and R4 are independently selected from the group consisting of hydrogen, alkyl, and heteroatom-substituted alkyl and R2 and R3 are independently selected from the group consisting of alkyl and heteroatom-substituted alkyl; and X1 and X2 (1) are independently selected from the group consisting of halogen, cyano, COOR7, -S-COR7, -OCOR7, (wherein R7 is alkyl or aryl), amido, -S-C6H5, carbonyl, alkenyl, or alkyl of 1 to 15 carbon atoms, or (2) taken together, form a ring structure of five to seven members with the nitrogen.
