摘要：
The thermally induced decomposition of ethoxyethynyl (trimethyl)tin (1) was studied by Sn-119 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)Delta(12/13)C(Sn-119) are provided for 1- 3. The first example of ultra-high resolution Sn-119 NMR is shown.
