PROBLEM TO BE SOLVED: To provide an ionic liquid having broad liquid range, high temperature stability and low corrosiveness and useful as a solvent for organic syntheses and an electrolyte liquid of an electrochemical battery.
SOLUTION: The ionic liquid is expressed by general formula K+A- (K+ is selected from a group composed of specific cations; and A- is selected from a group composed of specific anions). Concrete example of the ionic liquid is shown by the following formula.

PROBLEM TO BE SOLVED: To obtain a new compound useful for the production of a polymer precursor excellent in solubility and capable of producing, on a substrate, after cyclized, polybenzoxazole or polybenzothiazole having low hygroscopicity, high temperature stability and high planar formation degree. SOLUTION: This compound is expressed by formula I A<1> to A<3> are each H, CH3 or the like; T is O or S; Z is expressed by formula II to IV [Q is N or C-A (A is H, F or the like); up to 3 N atoms can exist and 2 N atoms thereof can be adjacent to each other on a separated aromatic ring, while up to 2 N atoms can exist per ring on a polycyclic system; M is a single bond, CH(CH3 ) or the like] or the like}, for example, 4,4'-bis(4-amino-3-hydroxy- phenoxy)-octafluorobiphenyl. The compound of formula I is obtained, e.g. by reacting a halogen compound of the formula X-Z-X (X is a halogen) with a compound of formula V (R is a residue, such as <=6C alkyl) in the presence of a base at 20-100 deg.C, and reducing the resultant dinitro compound to the corresponding diamino compound and eliminating the group R. |

NEW MATERIAL:A compound of formula I (A is alkylene having two carbon atoms bonded to alkyl groups and having a total carbon number of ≥5; R
2 is acyl, alkoxycarbonyl, acylalkyl, N-alkyl-substituted carbamoylalkyl, alkenyl, etc.; (m) is 1-3).
EXAMPLE: 3-Aminocrotonic acid 3-(4-allyl-1-piperidinyl)-2.2-dimethylpropyl ester.
USE: Useful as an intermediate for synthesizing 1,4-dihydropyridine derivatives having vasodepressor activity, vasodilation activity, etc.
PREPARATION: A compound of formula II is reacted with diketene (ketene dimer) of formula III in the presence of a base (e.g. pyridine) in a solvent such as methylene chloride or in the absence of the solvent at -10 to 130°C to prepare a compound of formula IV, which is reacted with ammonia gas or with a solution of solvent such as methanol saturated with ammonia to provide the compound of formula I.
