Abstract:
A cyanobiphenyl compound represented by the following formula (1): wherein R1 is a hydrogen atom, a C1-C8 alkyl group, an aryl group or an aralkyl group; X is a carboxyl group, a C1-C8 alkoxycarbonyl group, an aryloxycarbonyl group, an aralkoxycarbonyl group, a formyl group, the formula:â€”CH2â€”Y wherein Y is a chlorine atom, a bromine atom, an iodine atom, an azide group, â€”OR2 wherein R2 is a hydrogen atom, a C1-C8 alkylsulfonyl group optionally substituted with more halogen atoms, an arylsulfonyl group or 4-piperidinomethyl group wherein a nitrogen atom in the 4-piperidinomethyl group may be substituted with a C1-C8 alkyl group, a C1-C8 alkylcarbonyl group, an arylcarbonyl group, a C1-C8 alkoxycarbonyl group, an aryloxycarbonyl group or an aralkoxycarbonyl group, or â€”NHR3 wherein R3 is a hydrogen atom or a 4-piperidinomethyl group and wherein a nitrogen atom in the 4-piperidinomethyl group may be substituted with a C1-C8 alkyl group, a C1-C8 alkylcarbonyl group, an arylcarbonyl group, a C1-C8 alkoxycarbonyl group, an aryloxycarbonyl group or an aralkoxycarbonyl group, the formula: wherein Z1 and Z2 are each independently a chlorine atom, a bromine atom or an iodine atom, or the formula: wherein R4 and R5 are each independently a hydrogen atom, a C1-C8 alkyl group or a C1-C8 alkylcarbonyl group or both together may form a ring when R4 and R5 are each a C1-C8 alkyl group, or its salts thereof.
