Hypothesis
The study investigates the ligand scrambling reaction of R3PAuC15N to form (R3P)2Au+ and Au(C15N)2.
Conclusion
The study found that different R groups in R3PAuC15N complexes affect the NMR resonances and equilibrium constant.
Supporting Evidence
- Two 31p NMR resonances were observed for R3PAuCN and (R3P)2Au+ species.
- Only averaged resonances were observed for R3PAuC15N and Au(C15N)2 species except for Et3PAuC15N, where two resonances were detected.
- The equilibrium constant (Keq) was measured to be 0.14 between -60C to -40C for Ph3PAuCN.
- 3j (31p.15N) values were found to be 3.62, 2.93, and 4.02 Hz for different R groups.
Takeaway
The researchers looked at how certain gold compounds change when mixed, and they found that different ingredients make them behave differently.
Methodology
The reactions were studied using 15N and 31p NMR spectroscopy.
