N-Methylnitrilium trifluoromethanesulphonate nitrile and @-unsaturated nitriles is slow, and is usually (triflate) salts, prepared from nitriles and methyl triflate, accompanied by s-triazine formation. This nitrile cyclohave been shown to be useful reagents for the synthesis of trimerisation reaction is probably catalysed by a trace of aromatic ketimines and ketones, amidinium, imidate, and triflic acid which is difficult to remove completely from the thioimidate salts, benzimidazoles, benzoxazoles, benzo-methyl triflate, prepared from triflic acid and dimethyl thiazoles, quinazolinones, and 1,2,4-triazolinium salts.su1phate.l p 2 Triazine formation with benzonitrile and acrylonitrile can be reduced to insignificant levels by 1
