The thermally induced decomposition of ethoxyethynyl(trimethyl)tin (1) was studied by 119Sn NMR which revealed the formation of bis(trimethylstannyl) ketene (2) as the major product, bis(trimethylstannyl) acetic acid ethyl ester (3) as a minor product, and a small amount of tetramethyltin (4). Full NMR data sets, including coupling constants and isotope induced chemical shifts 1 Δ12/13C(119Sn) are provided for 1-3. The first example of ultra-high resolution 119Sn NMR is shown.
