C2H5, n-C3H7, Si(CH3)3 and unsymmetrical (R CH3, R′ Si(CH3)3) alkynes (RCCR′). Under similar experimental conditions, the ynamine, diethylaminotrimethylsilylethyne, led to a regioselective reaction. From the X-ray structure of the zirconaindene product, the trimethylsilyl group was found close to the zirconium atom. Compounds 4 with germanium tetrachloride afford new 1-germaindenes (7) characterized
几个1- zirconaindenes(4)已通过与各种对称加热phenylmethylzirconocene获得轻易(RR'CH 3,C 2 H ^ 5,NC 3 ħ 7,硅(CH 3)3和不对称(RCH 3, R'Si(CH 3)3)炔烃(RCCR')。在相似的实验条件下,乙胺基二乙氨基三甲基甲硅烷基乙炔导致区域选择性反应。在锆原子附近发现三甲基甲硅烷基。化合物4与四氯化锗可制得新的1-锗烷(7)通过1 H和13 C NMR和质谱法表征,收率良好。
