Method for preparation of tricyanidofluoroborates in 2 steps

The invention discloses a method for the preparation of tricyanidofluoroborate in two steps via tetra alkylammonium and tetra alkylphosphonium tricyanidofluoroborate, starting from tetraalkylammonium or tetra alkylphosphonium tetrafluoroborate and trimethylsilylcyanide in the first step and exchanging the cation in the second step.

Thermolyses of 1,1-dimethyl-2-pyrazolinium fluoborates - Evidence for spiro--1-aza-1,4,6-octatrienyl cation

Thermolyses of 3-aryl-1,1-dimethyl-2-pyrazolinium fluoborates give an isomeric mixture of 3-aryl-1-methylpyrazole and 5-aryl-1-methylpyrazole as major products in complete contrast to the corresponding acyclic analogs. 2,6-Diaryl-3-methylpyridines were isolated only in trace quantities.The probable reasons for this unique behaviour was explored using semi-empirical calculations, non-kinetic methods and radiolabelling experiments.A pathway was proposed.
