Reactions of P4 and I2 with Ag[Al(OC(CF3)3)4]: From elusive polyphosphorus cations to subvalent P3I6+ and phosphorus rich P5I2+
Krossing, Ingo
, p. 500 - 512 (2002)
Reactions of X2 (X = Br, I), P4 and Ag(CH2Cl2)[Al(OR)4] [R = C(CF3)3] in suitable ratios to prepare naked polyphosphorus cations were carried out and led to products which sugges
