An unexpected dependence on the SnII base; reactions of Sn(NR2)2 with aromatic dithiols†
Abstract
Unexpectedly, the reactions of the SnII base Sn(NMe2)2 with 1,2-benzodithiols [L(SH)2] do not give the stannylenes, L(S)2Sn, which are generated with Sn{N(SiMe3)2}2, instead the ion-separated SnIV compounds [Sn{L(S)2}]2−2[R2NH2]+ are formed in high yields.
