Abstract:
A method of manufacturing a cyclobutenedione compound represented by Formula (I) ##STR74## which is an (E) form, a (Z) form, or a mixture of the (E) and (Z) forms, wherein p is 1 or 0, E.sup.5 is a carbon atom or a nitrogen atom, in the case where E.sup.5 is a carbon atom, p is 1, D is a substituent having a Hammett substituent constant .delta.0.sup.R which is 0 or a negative value, in the case where E.sup.5 is a nitrogen atom, p is 0, m' is an integer 1 or 2, n' is any one of integers from 0 to 3, l' is any one of integers 0, 1 and 2, in the case where l' is 2, two m' in the formula may be the same or different from each other, R.sup.1 is an alkyl group having 1 to 4 carbon atoms and C* is an asymmetric carbon atom, comprising the step of allowing a cyclobutenedione compound represented by the following Formula (III) and a compound represented by the following Formula (IV) to react with each other: ##STR75## wherein X is a halogen atom, R.sup.1 is an alkyl group having 1 to 4 carbon atoms and C* is an asymmetric carbon atom, ##STR76## which is an (E) form, a (Z) form, or a mixture of the (E) and (Z) forms, wherein p is 1 or 0, E.sup.5 is a carbon atom or a nitrogen atom, in the case where E.sup.5 is a carbon atom, p is 1, D is a substituent having a Hammett substituent constant .delta.0.sup.R which is 0 or a negative value, in the case where E.sup.5 is a nitrogen atom, p is 0, m' is an integer 1 or 2, n1 is any one of integers from 0 to 3, l' is any one of integers 0, 1 and 2, and in the case where l' is 2, two m' in the formula may be the same or different from each other.
