The crystalline dilithium diphosphide [Li(tmeda)]2[C6H4(PR)2-1,2]1[R = SiMe3, obtained from C6H4(PRRâ³)2-1,2 (Râ²= Râ³= H or R, or Râ²= H and Râ³= R)] reacts with H2O, SiCl3Me, or [Zr(η-C5H3R2-1,3)2Cl2] to yield rac- and meso- C6H4(PHR)2-1,2, C6H4(PR2)2-1,2, or [[graphic omitted]R)2-1,2}], respectively; whereas 1 with RR-Me2C(OÄHCH2OTs)2(Ts = toluene-p-sulfonate) or SiButCl3 affords C6H4[[graphic omitted]H2-RR]2-1,2 or [[graphic omitted])-1,2}]3(µ3-SiBut), respectively.
结晶的二磷酸二锂[Li(tmeda)]2[C6H4(PR)2-1,2]1[R=SiMe3,由C6H4(PRRâ³)2-1,2(Râ²= Râ³= H或R、或 Râ²= H 和 Râ³= R)]与 H2O、SiCl3Me 或 [Zr(Î--C5H3R2-1,3)2Cl2] 反应,分别生成 rac- 和 meso- C6H4(PHR)2-1,2、C6H4(PR2)2-1,2 或 [[图形省略]R)2-1,2}];而 1 与 RR-Me2C(OÄHCH2OTs)2(Ts = 对甲苯磺酸盐)或 SiButCl3 反应,则分别得到 C6H4[[图形省略]H2-RR]2-1,2 或 [[Graphic omitted])-1,2}]3(µ3-SiBut) 。
