Dr. Armstrong et al., Electrophilic ring-opening of [(RP)(n)As](-) anions; a simple route to functionalised neutral phosphines of the type [((BuP)-P-t)((BuRP)-R-t)(2)], CHEM COMMUN, (24), 2000, pp. 2483-2484
Ring opening of the cyclic [((BuP)-P-t)(3)As](-) anion results from reactio
ns with electrophiles (RX = H2O, MeI, CH2=CHCH2I, PhCH2Br), providing a sim
ple and general approach to triphosphine ligands of the type [((BuP)-P-t)((
BuRP)-R-t)(2)].
