Iminophosphane

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… Witrynadmfu)(P N)] with one equivalent of the iminophosphane P N, followed by trans-metallation of the product [PdI(C 6H 4CF 3-4)(P N)] and by fast reductive elimination of the alkyne PhC CC 6H 4CF 3-4 to regenerate the starting palladium(0) compound. With [Pd(η2-dmfu)(P N)] as the catalyst, the oxidative addition is the rate-determining step,
