• Silver salt soluble in ether, fairly soluble in benzene and toluene, less soluble in acetonitrile and insoluble in chloroform and dichloromethane; useful, e.g. in promotion of the leaving ability of halogens.

• Acyl halides are converted to acyl triflates, powerful acylating reagents, which can bring about Friedel-Crafts-type acylation without added Lewis acid catalyst: Chem. Ber., 116, 1195 (1983).
• Reaction with chlorosilanes gives silyl triflates, powerful silylating reagents, and, likewise trialkyltin halides are converted to the corresponding triflates: Chem. Ber., 103, 868 (1970).
