From phosphanylphosphaalkenes to coordination copper and silver polymers containing P-P bonds

Area of Science:

• Organometallic Chemistry
• Coordination Chemistry
• Materials Science

Background:

• The activation of phosphorus-carbon (C-P) bonds is crucial for developing new synthetic methodologies.
• Exploration of reactions involving organophosphorus compounds with diols and dithiols can lead to novel molecular architectures.

Purpose of the Study:

• To investigate the activation of the C-P bond in Ph2C-P-PtBu2 via reactions with 1,6-hexanediol and various dithiols.
• To synthesize new organophosphorus compounds and subsequently develop coordination polymers using these compounds.

Main Methods:

• Reactions of Ph2C-P-PtBu2 with 1,6-hexanediol and dithiols (1,4-butanedithiol, 1,4-benzenedithiol, 1,4-benzenedimethanethiol).
• Utilizing a 1,2-addition mechanism for bond activation and compound formation.
• Subsequent reaction of synthesized compounds with metal chlorides (copper(I) and silver(I)) to form coordination polymers.

Main Results:

• Successful activation of the C-P bond and synthesis of four new organophosphorus compounds (2, 3a, 3b, 3c).
• Formation of coordination polymers of copper(I) and silver(I) from compounds 3a and 3c.
• All synthesized compounds exhibited stability under atmospheric conditions.

Conclusions:

• The study demonstrates an effective method for C-P bond activation using diols and dithiols.
• The synthesized organophosphorus compounds serve as effective ligands for the construction of metal coordination polymers.
• The resulting coordination polymers are stable, indicating potential for practical applications.
