Description
さらに、Ar1〜Ar4が置換基を有する場合、その置換基としては、1以上10以下の炭素原子を有し、かつHammett則における置換基定数σPが0.20以下である置換基が好ましい。その置換基はヘテロ原子を有していてもよい。ここで、Hammett則は、芳香族化合物における置換基が芳香環の電子状態に与える効果を説明するために用いられる経験則であって、置換ベンゼンの置換基定数σPは、置換基の電子供与/求引の程度を定量化した値といえる。σP値が正であれば置換安息香酸の方が無置換のものより酸性が強い、つまり電子求引性置換基となる。逆にσP値が負であると電子供与性置換基となる。表1は、代表的な置換基のσP値である(日本化学会編、「化学便覧 基礎編II 改訂4版」、丸善株式会社、平成5年9月30日発行、p.364〜365)。
Further, when Ar 1 to Ar 4 have a substituent, the substituent includes a substituent having 1 to 10 carbon atoms and having a substituent constant σ P in the Hammett rule of 0.20 or less. preferable. The substituent may have a hetero atom. Here, the Hammett rule is an empirical rule used to explain the effect of a substituent in an aromatic compound on the electronic state of the aromatic ring, and the substituent constant σ P of the substituted benzene is the electron donation of the substituent. / the extent of the required argument it can be said that the quantified value. sigma P value is more of substituted benzoic acid if positive acidic is stronger than that of the unsubstituted, that is, electron-withdrawing substituents. Conversely, when the σ P value is negative, an electron donating substituent is formed. Table 1 shows σ P values of typical substituents (The Chemical Society of Japan, “Chemical Handbook, Basic Edition II, 4th revised edition”, Maruzen Co., Ltd., published on September 30, 1993, p.364-365. ).
