Research Abstract	有機反応の電子的要因に関する理論の精密化と反応予測のグループでは、ペンタ-1,4-ジェンの環化反応の経路(諸熊)や、フラーレン類への付加反応の反応経路(永瀬)、イオンの溶媒和(西本)の理論的解明と予測を行った。反応速度論の立場からは、ベンジル誘導体の加溶媒分解の共鳴要求度と反応機構の関連性(都野)、芳香族アルデヒトやケトンの求核付加反応の同位効果と遷移状態の構造(山高)、基質-試薬錯体間の相互作用(速水)、高粘度媒体中での反応に対する圧力効果(浅野)、スルフェン酸の水溶液中での反応(奥山)に関する新知見を得た。有機反応の立体因子の定量的解析と反応予測への応用のグループでは、一方では立体効果の評価に分子力学を応用して、新しい立体置換基定数Ωsを定義しヘテロ原子を含む置換基に応用し(広田・榊原)、トリスホモキュバン二量体等の立体的混雑オフインに対するハロゲンの求電子反応の立体的経路の解明(大沢)を行った。他方では、STECARの概念に対する実験的証明(手塚)、BINAP-Ru(II)による不整水素化反応経路(野依)、高歪化合物の構造と反応の関連性(西田)など実験的立場から反応の立体的経路の解明を行った。反応中間体の構造と相互作用のグループは、(i)α-アリールビニルカチオン(谷口)、ビシクロ環系のα-ケトカチオン(竹内)およびトリプチセン類(山本)の構造と新しい性質の設計についての研究、(ii)電子移動により開始される反応(永田)の機構解明、(iii)超音波照射による反応のスイッチングと選択的反応の設計への応用(安藤喬)について成果を収めた。複雑な有機分子系の反応解析のグループは、シリセニウムイオン等の有機珪素化合物(吉良)、ポリシラ環状アセチレン及びオレフィン(安藤亘)、超原子価化合物(秋葉)、キラルなビスムチン(鈴木)、高周期ヘテロ原子化合物(岡崎)、〔3.3〕メタシクロファン(稲津)、生体関連化合物(大野)の分野で成果を収めた。
