Treating 1,3-dichloro-2,4-bis[tris(trimethylsilyl)silyl]-cyclo-diphosphadiazane, [HypNPCl](2) ((Me(3)Si)(3)Si = Hyp), or N-(2,4,6-tri-tert-butylphenyl)imino(chloro)phosphane, Mes*-N=P-Cl (Mes* = 2,4,6-tri-tert-butylphenyl), with Ag[Al(OCH(CF(3))(2))(4)] leads to the abstraction of [OCH(CF(3))(2)] from the counter ion [Al(OCH(CF(3))(2))(4)] in a formal Lewis acid/Lewis base reaction. The final products Hyp(2)N(2)P(2)(Cl)-(OCH(CF(3))(2)), Mes*-N=P-OCH(CF(3))(2) and the dimeric Lewis acid [Al(OCH(CF(3))(2))(3)](2) have been characterized by means of X-ray analysis.
