From Five to Seven: Ring Expansion of Monoazadiene Titanium Complexes by Insertion of Aldehydes, Ketones and Nitriles

The ring enlargement reactions at ambient temperatures of non C‐terminus substituted monoazabutadiene (η4−RN=CHCH=CH2) titanium complexes 2 are investigated. The insertion of aldehydes/ketones (five examples) and nitriles (four examples) into the Ti−C bonds result in expansion of the five‐membered r...
