Abstract: The electronic structures and nature of silicon-chalcogen double bonds SidX (X ) O, S) with
four-coordinate silicon in the unique silanoic silylester 2 and silanoic thioester 3 have been investigated for
the first time, by 29
Si solid state NMR measurements and detailed DFT and ab initio calculations. 29
