HCID 10305KyaphenineYield 68%

Procedure

Chlorosulfonic acid has been shown to be an effective catalyst for the trimerization of benzonitrile, providing a 68 percent yield of 2,4,6-triphenyl-s-triazine (J. Chem. Soc., 1941, 278). However, as shown in the following example, chlorosulfonic acid is ineffective to trimerize isobutyronitrile.
