TRIAMIDOSTANNATES(II) AS NUCLEOPHILES - SYNTHESIS OF ALLYLTRIAMIDOSTANNANES

A series of triamido stannanes of the general types HC{SiMe2NR}(3)SnCH 3 [R = p-Tolyl (3), t-Butyl (4)] and MeSi{SiMe2N(R)}(3)SnR' [R = p-Tol yl 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 }(3)SnLi(THF)(n)] and [MeSi{SiMe2NR}(3)SnLi(THF)(n)] with the respecti ve alkyl halides. For HC{SiMe(2)NtBu}(3)SnCH3 a single crystal X-ray s tructure analysis established the detailed structural arrangements in this new class of compounds. (C) 1998 Elsevier Science Ltd.
