    • However, vinylsamarium reagents had been generated from acyclic (Z)-α-chloroenones with samarium diiodide and treated with (reactive) aldehydes and ketones, and lithium reagents had been formed from ethylene acetals of α-chlorocyclohexenone with lithium and di-tert-butylbiphenyl and similarly treated.
