The stannyl anion 2, generated from Me3SiSnBu3(1)6 in the presence of R4NX, CsF or TASF [(Et2N)3SSiMe3F2]7 in DMF under very mild conditions, was used for 1,1-, 1,2-,or 1,4-elimination of an aryl or vinyl halide with an appropriate leaving group at the α-, β-, or δ-position of halogen. Thus, alkylidene carbene 8 is generated from 1,1-dibalo-alkene 6 or 7 and benzyne 10 is generated from 1,2-dibromobenzene 9 and an o-quinodimethane 12 was produced from α,α'-dibromoxylene 11a.
