Aromatic Phosphorus Heterocycles,. Thus, in many systems carbon can be replaced efficiently by phosphorus. The versatility is a consequence of the many different bonding modes available for the pnicogen element. The extent of the aromaticity is different with the different bonding modes, and can also be fine tuned by utilizing vari作者: 染色體 時(shí)間: 2025-3-22 02:03 作者: ELUC 時(shí)間: 2025-3-22 05:18

Chemistry of Hetero Analogs of Pentalene Dianion, simple five-membered heterocycles leading to four structures containing one heteroatom in each ring. The heteroatoms may be the same or different and may be O, NH, S, Se, Te, P, As, or Sb. The fully conjugated hetero analogs of pentalene dianion have a central C–C bond and are isoelectronic with th作者: Instinctive 時(shí)間: 2025-3-22 15:38 作者: 向外才掩飾 時(shí)間: 2025-3-22 19:57 作者: Lineage 時(shí)間: 2025-3-22 22:53 作者: PHIL 時(shí)間: 2025-3-23 05:17
