摘要: Insertion of the intermediately formed carbene-analogous PX24 ion (X = Br, I) into one P-P bonds P4 tetrahedron led to P5X2+ - 1st example previously unknown class phosphorus-rich binary P-X cations. The crystal structure [P5Br2]+[Al{OC(CF3)3}]- was detd. and mol. calcns. were performed on both bromide iodide analogs. [on SciFinder (R)]
