Thietane and selenetane complexes by thermal cycloaddition of vinyl ethers to transition metal coordinated thio- and seleno-aldehydes
Abstract
Pentacarbonyl tungsten coordinated thio- and seleno-benzaldehydes react with vinyl ethers by regiospecific addition of the CC to the XC bond of the heteroaldehydes to form thietane and selenetane complexes, respectively.
