✦ Synopsis

3-Methyl-2-butenenitrile (1) cyclodimerised on treatment with lithium diisopropylamide in dimethoxyethane at temperatures between -78Β°C and 0Β°C to 3-amino-4-cyano-1,5,5trimethyl-1,3-cyclohexadiene (2) the structure of which was established by acid hydrolysis to the known 4-cyano-1,5,5-trimethyl-1-cyclohexene-3-one (3).

The catalytic isomerization of 2-methyl-3-butenenitrile (2M3BN) was performed in the presence of Ni(0) with N-heterocyclic carbene (NHC) ligands. On using bulky aromatic substituents on the NHC nitrogen atoms, the isomerization reaction proceeded at room temperature within 15 min: a total conversion
