Thermally robust metallacycles [M(η-C5H5)2L] ( L [(2-CH2C6H4)2]2−, M Ti, Zr, Hf) and [SnPh2L] have been obtained from the newly developed reagents, L[MgCl(thf)n]2 and L[Li(tmeda)]2, as has the silylated derivative, [2-(Me3SiCH2)C6H4]2. A new radical anion of 9,10-dihydrophenanthrene derived from the reaction of lithium and LCl2 or LBr2 in thf has been detected.
热鲁棒metallacycles [M(η-C 5 H ^ 5)2 L](L[(2- CH 2 C ^ 6 ħ 4)2 ] 2-中,M钛,锆,铪)和[SnPh 2 L]有从新开发的试剂L [MgCl(thf)n ] 2和L [Li(tmeda)] 2中可以获得甲硅烷基化衍生物,[2-(Me 3 SiCH 2)C 6 H 4 ] 2也是如此。锂与LCl 2或LBr 2反应衍生的9,10-二氢菲新自由基阴离子 已检测到。
