| Abstract: | The synthesis and characterization of a series of tricarbastannatranes, in the solid state and in solution, are described. The structures of the complexes [N(CH2CH2CH2)3Sn](BF4), [N(CH2CH2CH2)3Sn](SbF6), [N(CH2CH2CH2)3Sn]4[(SbF6)3Cl], and [(N(CH2CH2CH2)3Sn)2OH][MeB(C6F5)3] were determined by X‐ray crystallography. Furthermore, the B(C6F5)3‐promoted conjugate addition of alkyl‐tricarbastannatranes to benzylidene derivatives of Meldrum’s acid was investigated, and detailed mechanistic studies are presented. |
