Trimethyloxonium 2,4,6-trinitroBENZENESULFONATE

This facile preparation is suitable for preparation of larger amounts of salt Like triethyloxonium fluoborate,2 trimethyloxonium fluoborate is a potent alkylating agent. In comparison with trimethyloxonium 2,4,6-trinitrobenzenesulfonate,5trimethyl-oxonium fluoborate is easier to make but does not keep quite as well on storage. 

This method for the preparation of trimethyloxonium 2,4,6-trinitrobenzenesulfonate is an adaptation of that described by the submitters.7 The salt can also be prepared from trimethyloxonium fluoborate by anion exchange.7 Trimethyloxonium fluoborate and hexachloroantimonate9-11 have been prepared by other methods. 

Like triethyloxonium fluoborate,12 trimethyloxonium 2,4,6-trinitrobenzenesulfonate is a potent alkylating agent. Tri-... 

Trimethyloxonium 2,4,6-trinitrobenzenesulfonate [1, 1232-1233, before reference]. This stable alkylating agent is prepared by the method cited1 and also by reaction of the acid with trimethyloxonium fluorohorate (71-76% yield).2 The salt can be kept...
