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.


Helpful experimental; Some discrepancies observed in NMR

The article reports the catalytic isomerization of the branched cyanoolefin 2-methyl-3-butenenitrile (2M3BN) to the linear isomer 3-pentenenitrile (3PN) using nickel-phosphine complexes.

The authors report that the optimal catalytic experiment was carried out by adding...
