摘要：

Treatment of the silylene Si[C6H4(NCH2But)(2)-1,2] with SnAr2 or SnAr[N(SiMe3)(2)] yields the thermally stable (silyl)stannylene SnAr[Si{C6H4(NCH2But)(2)-1,2}X] [X = Ar 1 or N(SiMe3)(2) 2], having delta [Sn-119{H-1}] 412 [(1)J((SiSn)-Si-29-Sn-117/119) 715/749 Hz] (1) and delta 621 (2); crystalline 1 has a V-shaped Si-Sn-C skeleton, l(Sn-Si) = 2.636(2) Angstrom and two remote Sn ... N contacts, av. 2.75 Angstrom (to one NMe2 group of each of the aryl groups).
