A. Hafid et al., SYNTHESIS AND REACTIVITY OF (C5H4PPH2, BH3)2U(BH4)2 AN UNUSUAL ELECTRON-POOR CYCLOPENTADIENYL COMPLEX, New journal of chemistry, 18(5), 1994, pp. 557-559
Borane complexation on the phosphorus atom of diphenylphosphidocyclope
ntadienyl-uranium complexes modelized f-d heterobimetallics with the d
metal bonded to the phosphorus. Like the d metal moiety, the coordina
ted borane induces a strong electron withdrawing effect.
