Research Abstract

「反応中間体の化学」をテーマとした物理有機化学の国際会議が、筑波大学、大学会館で、招待外国人14人、招待日本人15人と一般参加者69人の参加を得て開催された。講演は(1)新しい異常原子価反応活性種の創製とその物理化学的性質、(2)反応中間体の生成とその化学的挙動、(3)異常な電荷やπ-共役系を有する反応中間体の生成を中心として、特別講演10件、口頭発表21件、ポスター発表42件あった。この会議では、反応中間体の生成として、極限条件下、特に真空超高温、極低温マトリックス中での光反応を利用してのカルベン、シリレン、ゲルミレン、セルニレン等の原子欠損型の中間体についての研究から論じられ、その構造や反応性に興味ある報告がなされた。また反応中間体の速度論的研究が検討され、その結合状態に新しい知見を与えている。一方、ラジカルイオン種の生成が電子移動の反応を通して検討され、ヘテロ原子の特性を利用した新しいπ-電子系の構築による、新規機能材料の開発で興味ある結果が報告された。現在活性分子には高歪みや反芳香族性、原子欠損型分子などいろいろあるが、なかでも14属元素を含む活性種は最も注目され、そのせいかもめざましいものがる。ジシラシクロペンの光、および熱によるジシラベンズヴァレンへの異性化、ケイ素の3重結合の理論的考察、またフラーレンを中心とするケイ素化合物の生成など、新しい活性種がみられている。
