Transmetallation reaction of trisilylstannane ArSn(SiHMe(2))(3) (Ar = 2,6-bis(2,4,6-triisopropylphenyl)phenyl), bearing a bulky substituent on the tin atom, with methyllithium in THF at room temperature gave the first trianion equivalent, trilithiostannane ArSnLi(3), the generation of which was confirmed by trapping experiments with some electrophiles as well as by (119)Sn and (7)Li NMR spectroscopy
三甲硅烷基锡烷ArSn(SiHMe(2))(3)(Ar = 2,6-双(2,4,6-三异丙基苯基)苯基)在室温下与甲基锂在THF中的金属转移反应给出了第一个三价阴离子等效物,三硫代锡烷ArSnLi(3),其生成通过一些亲电试剂的俘获实验以及(119)Sn和(7)Li NMR光谱证实。
