Novel imidazolium compounds of the formula ##STR1## wherein A represents the atomic group necessary to form a heteroaromatic ring, which may be optionally substituted by one or more R substituents selected from the group consisting of aryl, heteroaryl, lower alkyl, hydroxy, halide, or carboxy substitutents; B is an optional substituent which represents the atomic group necessary to form a heteroaromatic ring or a double or triple carbon-nitrogen bond, which may optionally be substituted by one or more R' substituents selected from the group consisting of aryl, heteroaryl, lower alkyl, hydroxy, halide, or carboxy substitutents; C is an optional substituent which represents the atomic group necessary to form an aromatic or heteroaromatic ring, which may optionally be substituted by one or more R"" substituents selected from the group consisting of aryl, heteroaryl, lower alkyl, hydroxy, halide, or carboxy substituents; R" and R'" are each independently a lower alkyl or aryl group, or together with the nitrogen atom to which they are attached, form a heterocyclic ring having from 5 to 7 members, which may optionally contain a sulfur, oxygen, silicon, selenium or an additional nitrogen atom; and X is an anion; are useful in a variety of industrial and medical applications.
新型咪唑化合物的化学式为##STR1##其中,A代表形成杂芳环所需的原子基团,该基团可以选择性地由取自芳基、杂芳基、较低烷基、羟基、卤素或羧基取代基团的一个或多个R取代基团替代;B是一个可选择的取代基,代表形成杂芳环或双重或三重碳-氮键所需的原子基团,该基团可以选择性地由取自芳基、杂芳基、较低烷基、羟基、卤素或羧基取代基团的一个或多个R'取代基团替代;C是一个可选择的取代基,代表形成芳香或杂芳环所需的原子基团,该基团可以选择性地由取自芳基、杂芳基、较低烷基、羟基、卤素或羧基取代基团的一个或多个R""取代基团替代;R"和R'"分别是较低烷基或芳基,或者与它们附着的氮原子一起形成具有5至7个成员的杂环,该杂环可以选择性地含有硫、氧、硅、硒或额外的氮原子;X是一个阴离子;在各种工业和医疗应用中具有用途。
