Organofunctionalized alkyltin bromides have been synthesized from solvochemically activated tin metal and the corresponding alkyl bromide under mild conditions (95°C) and without the use of a catalyst. This synthetic method tolerates a variety of functional groups such as chloride, cyanide, or a carboxylic ester and can be applied to different chain lengths. Crystal structure analysis of as‐prepared [(H 3 COOCC 2 H 4 ) 2 SnBr 2 ] shows a close‐to‐octahedral environment for the tin atom, created by intramolecular ring formation through the carbonyl groups of the two carboxylic ester functionalities. [(H 3 COOCC 2 H 4 ) 2 SnBr 2 ]: space group P2 1 /n, Z = 4, lattice parameters at 293 K: a = 10.32501(8) Å, b = 16.2350(1) Å, c = 8.14838(6) Å, b = 95.2319(5) °, R(F) = 0.056. The compound is isotypic to [(H 3 COOCC 2 H 4 ) 2 SnCl 2 ].
