複素環(huán)式化合物

複素環(huán)式化合物は分子中で環(huán)狀構(gòu)造を有する有機(jī)化合物の一種であり，環(huán)を構(gòu)成する炭素原子に加えて，一つ又は複數(shù)の窒素原子、硫黃原子、酸素原子等の他の原子を含有する。一つの環(huán)のみを含有すれば，単環(huán)式化合物と呼ばされ，例えばフラン、チアゾール、ピリジン；二つ又は二つ以上の環(huán)を含有すれば，多環(huán)式化合物と呼ばされ，例えばキノリン、プリン等。その中で性質(zhì)が最も穏やかでかつ最も一般的なのは5員又は6員複素環(huán)である。簡(jiǎn)単な複素環(huán)はベンゼン又は他の複素環(huán)と結(jié)合して二環(huán)、三環(huán)又はより複雑な環(huán)系を形成することができる。ある複素環(huán)は芳香族化合物の特性を有し，例えば置換反応を起こしやすく，付加反応を起こしにくく，酸化剤と合わせて使用する時(shí)にその化學(xué)的性質(zhì)が穏やかである。複素環(huán)式化合物は自然界に広く存在し，例えば核酸、ほとんどのビタミン、クロロフィル、ヘモグロビン、ほとんどのアルカロイド、色素等。一部の複素環(huán)式化合物は芳香族性を有し，例えば植物中のクマロン、シスジャスモン，動(dòng)物中のシベトン等?；瘜W(xué)合成農(nóng)薬中でこの種類の化合物は多く，例えば除草剤のアトラジン、アミトロール、イソメチオジン，殺蟲剤のプロパルギット、キナルホス，殺菌剤のトリクロロイソシアヌル酸、チオキノックス等。簡(jiǎn)単な複素環(huán)式化合物は有機(jī)化學(xué)工業(yè)の重要な原料である。環(huán)系を構(gòu)成する炭素原子に加えてO，S，N等のヘテロ原子を含有する環(huán)狀化合物は複素環(huán)式化合物と総稱される。この定義に従って，厳密には環(huán)形無水コハク酸、環(huán)形イミド、ラクトン、ラクチド、環(huán)形無水物、ラクタム、環(huán)狀エーテル等も複素環(huán)式化合物に屬し，しかしこれらの化合物は性質(zhì)が脂肪族と類似し，かつ鎖式化合物を縮合して取得しやすいとともに，開環(huán)から鎖狀化合物に変換しやすいため，一般的に脂肪族とともに検討する。そのため複素環(huán)式化合物は特に環(huán)系が穏やかでかつ異なる芳香族性を有する複素環(huán)式化合物を指し，即ち芳香族複素環(huán)化合物である。有機(jī)複素環(huán)式化合物は開鎖、炭素環(huán)、複素環(huán)という三種類の有機(jī)化合物の一種であり，その種類が膨大で，その數(shù)量が多く，すべての既知の有機(jī)化合物の約1/3を占め，かつ生物界に広く存在し，生物の成長(zhǎng)、発育、生殖、及び遺伝、変異等と密接な関係がある。通常の複素環(huán)式化合物はフラン、チオフェン、ピロール、キノリン、カルバゾール等を含む。これらの複素環(huán)式化合物は有機(jī)合成又は醫(yī)薬、農(nóng)薬、溶剤等に広く用いられる。無色でかつ特別な臭いを有する液體又は結(jié)晶であり，その比重が水より小さく又はそれに近く，毒性があり，いくつかの有機(jī)溶剤に溶解でき，水にわずかに溶解する?；鸱N、高熱、酸化剤及び強(qiáng)酸と接觸すると燃焼又は爆発を引き起こすことができ，それに毒性のある硫黃酸化物や窒素酸化物のガス?fàn)钗镔|(zhì)を析出する。フランは空気で過酸化物を形成し，蒸留すると爆発を引き起こすことができる。危険物の管理過程において，火災(zāi)、爆発、毒性の危険性の大きさによって，それぞれ可燃性液體、可燃性固體、有機(jī)有毒物質(zhì)に分類される；貯蔵と使用時(shí)に，その前の二種はA火災(zāi)、B火災(zāi)を引き起こす危険物として，後者はC火災(zāi)を引き起こす危険物として火災(zāi)管理を行う。発火時(shí)に，泡消火剤、粉末消火剤、水ミスト、1211、炭酸ガス消火剤等の消火剤を利用して消火を行うことができる。
