In organophosphorus chemistry, an aminophosphine is a compound with the formula R3−nP(NR2)n where R = H or an organic substituent, and n = 0, 1, 2. At one extreme, the parent H2PNH2 is lightly studied and fragile, but at the other extreme tris(dimethylamino)phosphine (P(NMe2)3) is commonly available. Intermediate members are known, such as Ph2PN(H)Ph. These compounds are typically colorless and reactive toward oxygen. They have pyramidal geo… Witryna16 kwi 2004 · The reaction of a trichloro iminophosphorane (Cl3P NtBu) and either a zirconaindane phospholane or an azazirconaindane phosphane proceeds in an unexpected fashion, with the trapping of a transient chlorophosphaimine species (Cl P NtBu), and the formation of unique metalla‐azaspirophosphanes (see picture). flag officer screeningWitryna13 paź 2009 · A common feature of all three structures is that they possess a highly electrophilic carbon centre (C-3 in 2 H-azirines, C-4 in conjugated nitroso- and azo-alkenes) that allows nucleophilic addition reactions to proceed very readily.In reactions of nucleophiles with 2 H-azirines this often leads eventually to opening of the three … flag officers 4 america website
