Reactions of 9-Triptyceneselenol with Palladium(0) Complexes: Unexpected Formations of the Dinuclear Palladium(I) Complex [{Pd(PPh3)}2(μ-SeTrip)2] and Five-Membered Selenapalladacycle [Pd(η2(C,Se)-Trip)(dppe)]
摘要:
The oxidative addition reaction of the overcrowded selenol TripSeH (1; Trip = 9-triptycyl) with [Pd(Ph3P)(4)] in toluene produced a novel dinuclear palladium(I) complex with bridging selenolato ligands, [{Pd(PPh3)}(2)(mu-SeTrip)(2)] (2). In contrast, the reaction of 1 with [Pd(dppe)(2)] in toluene resulted in the formation of the five-membered selenapalladacycle [Pd(eta(2)(C,Se)-Trip)(dppe)] (3).
