Jos Wilting, Christian Müller, Alison C. Hewat, Dianne D. Ellis, Duncan M. Tooke, Anthony L. Spek, Dieter Vogt
Organometallics | 2005 | 10.1021/om049206p

The isomerization of the branched 2M3BN to the linear 3PN by a DPEphosNi species has been investigated by means of variable-temperature NMR spectroscopy, and activation parameters have been determined. An intermediate in this reaction, which is formed via...

Isomerization of 2-methyl-3-butenenitrile to 3-pentenenitrile is catalyzed by nickel π-allyl cyanide complexes. The C−CN bond breaking is a key step in the catalytic mechanism, as evidenced by in situ NMR monitoring and DFT studies.
