The reactions of (E)-2-chloro(dimethyl)stannyl-3-diethylboryl-N,N-dimethyl-2-pentenylamine 2, containing penta-coordinate tin, with lithium diethylamide, -diiso-propylamide, -bis(trimethylsilyl)amide, with N-lithiated azoles (pyrrole, 1,2,4-triazole), and C-lithiated azoles (N-methylimidazole, thiazole and 4-methylthiazole) were studied. Most of the products 3–11 correspond closely to those obtained
