Electrophilic ring-opening of [(RP)nAs]− anions; a simple route to functionalised neutral phosphines of the type [(ButP)(ButRP)2]
Abstract
Ring opening of the cyclic [(ButP)3As]− anion results from reactions with electrophiles (RX = H2O, MeI, CH2CHCH2I, PhCH2Br), providing a simple and general approach to triphosphine ligands of the type [(ButP)(ButRP)2].
