Oxidative addition of diaryldichalcogenides to the diferrocenylphosphenium ion: synthesis, structure and organocatalytic activity†
Abstract
The reaction of the phosphenium ion [Fc2P]+ with dichalcogenides gace rise to the respective phosphonium ions [Fc2P(ChR)2]+ (Ch = S, Se, Te; R = Ph, Fc, biphen), which were employed in chalcogen bond mediated Michael additions.
