Novel N-(phenyl)-1,4,5,6-tetrahydro-1,2,4-triazine-3-methanamines are disclosed which are useful as herbicides, insecticides, and antimicrobial agents. Various member compounds are also pharmacologically active.
Strecker reaction of formaldehyde, amines, and TMSCN that affords three-component coupling adducts as the major products is reported. HCOOH and TBAF are used as cocatalysts and the TMSCN functions as both cyanidesource and protecting reagent for amines. As a result, the side reactions were suppressed efficiently and a broad range of aromatic and aliphatic amines were mono-cyanomethylated in 52–99%
