Triamidostannates(II) as nucleophiles: synthesis of allyltriamidostannanes

A series of triamido stannanes of the general types HC{SiMe2NR}3SnCH3 [R = p-Tolyl (3), t-Butyl (4)] and MeSi{SiMe2N(R)}3SnR′ [R = p-Tolyl and R′ = CH2CHCH2 (5), CH2CHCHCH3 (6), CH2CHCHC6H5 (7), CH2(CH3)CCH2 (8); R = t-Butyl and R′ = CH2CHCH2 (9), CH2CHCHCH3 (10)] have been synthesized by reacting the lithium triamidostannates [HC{SiMe2NR}3SnLi(THF)n] and [MeSi{SiMe2NR}3SnLi(THF)n] with the respective alkyl halides. For HC{SiMe2NtBurcSnCH3 a single crystal X-ray structure analysis established the detailed structural arrangements in this new class of compounds.
