[W(η-C5H5)2HL][PF6], [W(η-C5H5)2(CH3)L][PF6](when L = py or MeCN). An α-elimination mechanism is proposed for these reactions. In a study of the related thermal reactions the products were the same as in the photochemical reactions for L = PMe2Ph; for L = py the sole product isolated was [W(η-C5H5)2(CH3)L][PF6]; and no reaction was observed with L = MeCN.
的照射[W(η-C 5 H ^ 5)2(CH 3)2 ] [PF 6 ]中的L [L =
吡啶(PY),
乙腈或二甲基苯基]导致了下列产物的分离的存在: [W(η-C 5 H ^ 5)2(CH 3)L] [PF 6 ],[W(η-C 5 H ^ 5)2 H(CH 2 L)] [PF 6 ](当L = PME 2 PH),和[W(η-C 5 H ^ 5)2 HL] [PF 6 ],[W(η-C 5 H ^5) 2(CH 3)L] [PF 6 ](当L = py或MeCN时)。对于这些反应,提出了α消除机理。在对相关热反应的研究中,对于L = PMe 2 Ph,产物与光
化学反应相同。对于L = PY分离的唯一产物是[W(η-C 5 H ^ 5) 2(CH 3)L] [PF 6 ]; 并且在L = MeCN下未观察到反应。
