Synthesis of the First 1,3,4-Triphosphole Complex
摘要:
Surprisingly selective is the preparation of the novel 1,3,4-triphosphole complex 1 by insertion of a phosphaalkyne into a 1H-diphosphirene complex. NMR spectroscopic experiments and quantum-mechanical calculations indicate a small P-inversion barrier for the σ3 -phosphorus center in 1 as well as new possibilities of "π-tuning".
