Colvin, Ernest W. published the artcileO-(Diphenylphosphinyl)hydroxylamine: a new reagent for electrophilic C-amination, SDS of cas: 5098-14-6, the publication is Tetrahedron Letters (1982), 23(37), 3835-6, database is CAplus.
Ph2P(O)ONH2 (I) efficiently aminated (EtO)2P(O)CH–CO2CH2Ph, (EtO2C)2CH–, (NC)2CH–, PhMgBr, and Me(CH2)5MgBr in THF at -78° under Ar. E.g., treatment of (EtO)2P(O)CH2CO2CH2Ph with NaH at room temperature under Ar, then I at -78° gave 60% (EtO)2P(O)CH(NH2)CO2CH2Ph.
