A simple and efficient one-step protocol for the preparation of alkyl-substituted ammonium tetrafluoroborate and hexafluorophosphate salts

• A highly facile one step protocol for the preparation of alkyl substituted ammonium tetrafluoroborate and hexafluorophosphate salts was developed.
• The broad scope of the protocol is demonstrated by the preparation of a wide range of BF4 and PF6 salts of primary, secondary and tertiary amines.
• The reaction is fast, uses inexpensive bulk chemicals, and leads to high purity products in high yields.
• The protocol does not require conversion of amine free bases to their chloride salts and avoids preparation of a precursor reagent.

A fast and high yielding one-step protocol using commercially available and inexpensive bulk chemicals is described for the preparation of a series of mono-, di-, and trialkyl-substituted ammonium tetrafluoroborate and hexafluorophosphate salts under nonaqueous condition.
