Abstract

Abstract: We will outline that the sign and magnitude of J (Si, H) coupling constants provide a highly sensitive tool to measure the extent of Si−H bond activation in nonclassical silane complexes. Up to now, this structure–property relationship was obscured by erroneous J (Si, H) sign determinations in the literature. These new findings also help to identify the salient control parameters of the Si−H bond activation process in nonclassical silane complexes.
