Useful:

• Chemical Classes: Metals -> Metals, Inorganic Compounds
• Canonical SMILES: [B-](F)(F)(F)F.[Ag+]
• Uses: Silver tetrafluoroborate finds applications as a useful reagent in inorganic, organic and organomettalic chemistry. It acts as a moderately strong oxidant in dichloromethane, replaces halide anions and ligands with weakly coordinating tetrafluoroborate anions, and behaves as a catalyst for cyclization reactions. It is a potent promoter for chemical glycosylation.

Technology Process of Silver tetrafluoroborate

There total 33 articles about Silver tetrafluoroborate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:
