项目摘要

光誘起電子移動反応条件でケイ素架橋化合物が反応活性種特にカチオンラジカル種を発生する可能性を検討した。この過程でケイ素-ケイ素結合の新しい光フッ素化開裂反応を見いだした。1.ケイ素架橋多環式化合物の異性化と反応活性種の捕捉9,10-ジシアノアントラセン存在下タングステン(W)ランプの照射で、ジベンゾシラノルボルナジエン誘導体(1)は骨格転位して2-シラ-3,4,6,7-ジベンゾビシクロ〔3.2.0〕ヘプタジエン異性体3をアントラセンと共に生成した。1およびジシラビシクロ〔2.2.2〕オクタジエン誘導体(2)は2,4,6-トリフェニルピリリウムテトラフルオロボラート(TPP^+BF_4^-)存在下のW-ランプ照射で形式的にケイ素架橋部に対応する反応活性ケイ素種がフッ素に捕捉されたジフルオロシランを与えた。2.光フッ素化開裂反応フェニルジシラン類およびオクタメチルトリシランはTPP^+BF_4^-存在下W-ランプを照射するとケイ素-ケイ素結合がフッ素化開裂を受け対応するフルオロシランを与えた。たとえば、1,2-ジフェニルテトラメチルジシランからはフルオロメチルジフェニルシランが定量的に得られる。この光フッ素化開裂はシクロヘキサシラン等の環状オリゴシランでも進行した。3.シロール類の設計と合成ジエン部分に置換基を持たないビストリメチルシリルシロールをはじめて合成した。

To explore the possibility of the generation of reactive species by photoinduced electron mobility This process is called prime-prime-bonding, and it is called prime-cracking. 1. Heterogeneity and capture of 9,10-bis-active species of heterocyclic compounds in the presence of bis-bridged heterocyclic compounds. Irradiation of (W)-bis-heterocyclic compounds.(1)-bis-heterocyclic compounds in the presence of bis-heterocyclic compounds.(2)-bis-heterocyclic compounds in the presence of bis-heterocyclic compounds.(3)-bis-heterocyclic compounds. 1. W-irradiation of the W-type elicitor in the presence of the 2,4,6-triphenyl elicitor (TPP^+BF_4^-) in the form of the elicitor bridging part of the anti-active elicitor species in the presence of the 2,4,6-triphenyl elicitor. 2. In the presence of W-ray irradiation, the reaction of light to element-induced cracking is affected by light to element-induced cracking.たとえば、1,2-ジフェニルテトラメチルジシランからはフルオロメチルジフェニルシランが定量的に得られる。The light of the light is divided into two parts: the light is divided into three parts: the light is divided into two parts: the light is divided into three parts: the light is divided into two parts: the light is divided into three parts: the light is divided into two parts: the light is divided into three parts: the light is divided into three parts: the light is divided into four parts: the light is divided into three parts: the light is divided into three parts: the light is divided into four parts: the light is divided into three parts: the light is divided into four parts: the light is divided into three parts: the light is divided into four parts: the light is divided into four parts: the light is divided into three parts: the light is divided into four parts: the light is divided into three parts: the light is divided into four parts: the light is divided into three parts: the light is divided into four parts: the light is divided into four parts: the light is divided into three parts: the light is divided into four parts: the light is divided into four parts 3.
