A substituted aromatic compound substituted with Q is obtained by reacting a phosphazenium compound represented by formula (1)
1
(in the formula,
Q
−
represents an anion in a form derived by elimination of a proton from an inorganic acid, or an active hydrogen compound having an active hydrogen on an oxygen atom, a nitrogen atom or a sulfur atom;
a, b, c and d, each independently, is 0 or 1, but all of them are not 0 simultaneously; and
R groups represent the same or different hydrocarbon groups having 1 to 10 carbon atoms, or two Rs on each common nitrogen atom may be bonded together to form a ring structure) with a halogenated aromatic compound having halogen atoms;
whereby, at least one halogen atom in the halogenated aromatic compound is substituted with
Q
(where, Q represents an inorganic group or an organic group in a form derived by elimination of one electron from Q
−
in formula (1)).
通过将式(1)1所代表的
磷氮化合物与含有卤原子的芳香化合物反应,可以得到一种被Q取代的取代芳香化合物(其中,Q-在公式中代表从
无机酸中去除质子或具有氧原子、氮原子或
硫原子上的活性氢的活性氢化合物所导出的形式的阴离子;a、b、c和d各自独立地为0或1,但它们不同时为0;R基表示具有1至10个碳原子的相同或不同的碳氢基团,或者在每个共同氮原子上的两个R可能被结合在一起形成环状结构)。因此,至少有一个卤原子被Q取代(其中,Q在公式(1)中代表从Q-中去除一个电子所导出的无机基团或有机基团)。
