Replacement of Aryl by Alkyl in 1-Substituted 1H-1,2,3-Triazole-4-carbaldehydes
L'abbe, Gerrit,Bruynseels, Maria
, p. 1492 - 1493 (2007/10/02)
1-Phenyl-1,2,3-triazole-4-carbaldehyde is readily transformed into 1-alkyl-1,2,3-triazole-4-carbaldehydes by thermal isomerization of the corresponding imines, followed by acid hydrolysis.
