Abstract

New iminophosphorane− phosphine Re (I) complexes have been synthesized and used for the catalytic isomerization of terminal propargylic alcohols into α, β-unsaturated enals or methylketones under neutral conditions, using the ionic liquid [BMIM][PF6] as a nonconventional solvent. This catalytic system could be recycled up to 10 consecutive times. Isolation and X-ray characterization of the key intermediate rhenium (I) oxacyclocarbene ...
