Sodium tetraphenylboron Usage
1. Analytical reagents for the determination of potassium, ammonium, rubidium, cesium, mercury, thallium and nitrogen-containing organic compounds
For example, analysis of scapular fat and potassium in blood;
2. Sodium tetraphenylborate can be used as a phenyl donor, cross-coupling with vinyl trifluoromethanesulfonate or aryl ester under palladium catalysis to generate aryl olefin or biphenyl derivatives in high yield;
3. The polycondensation catalyst for producing carbonate by transesterification;
