Abstract:
The reaction of Li[Mes*NH] (1, Mes* = 2,4,6-tri-tert-butylphenyl) with aminoarsane Mes*N(H)AsCl 2 (2, Mes* = 2,4,6-t-Bu 3 C 6 H 2 ) at −80 °C resulted in the formation of bisamino(chloro)arsane (Mes*NH) 2 AsCl (3Cl) by elimination of LiCl. 3Cl reacted with the Lewis acids such as AlCl 3 , GaCl 3 , and Ag[X] (X = AsF 6 − , OTf − , BF 4 − ; OTf = trifluoromethanesulfonate = OSO 2 CF 3 − ) upon chloride ion abstraction to give salts bearing the cation [(Mes*NH) 2 As] + (3[X]; X = AsF 6 − , OTf − , BF 4 − , ECl 4 ; E = Al, Ga). 3 + represents the first NH-functionalized acyclic bis(amino)arsenium cation. The formation of the salts bearing 3 + could also be observed in the reaction of cyclo-1,3-diarsa-2,4-diazane [ClAs(μ-NMes*)] 2 (4) with Lewis acids (AlCl 3 , GaCl 3 ) in the presence of proton sources in solution. All presented salts 3[X] were stable at room temperature and fully characterized.
