Abstract

Carbenic JC.H coupling as an indicator of agostic interactions in surface species: In the highly active heterogeneous catalyst for olefin metathesis 1, this coupling constant is 109 Hz for the syn and 159 Hz for the anti rotamer. From this, a H-agostic interaction in the syn rotamer can be deduced and the high electrophilicity of the Re center can be rationalized.
