title: Synthesis, structure and reactions of a trianion equivalent, trilithiostannane.
abstract: 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.
