## Abstract Redox transmetallation reactions between trimethyltin compounds, SnMe~3~L [L = 3,5‐diphenylpyrazolate (Ph~2~pz), 2,6‐di‐__tert__‐butyl‐4‐methylphenolate (OAr), or C~6~F~5~] and lanthanoid metals have yielded [Ln(Ph~2~pz)~2~(DME)~2~] (Ln = Eu, Yb), [Ln(Ph~2~pz)~3~(DME)~2~] (Ln = Y, La, N
Effective coupling of tin enamines I and ct-haloaldehydes 2 gave 2,4-disubstituted pyrroles in high yields at room temperature even under aqueous conditions. The reaction with 2bromoaeetophenone gave 3,4-disubstituted pyrroles, while the addition of HMPA changed the selectivity to afford the 2,4-iso
