2,5,6,8,9-Penta-alkyl or penta-aralkyl-substituted 1,3,7- triazabicyclo(3, 3,1) non-3-enes and trialkyl or triaralkyl-substituted tetrahydropyrimidines

摘要

This invention relates to the preparation of penta-alkyl (or aralkyl)- substituted 1,3,7-triazabicyclo (3,3,1) non-3-enes (TBN's) and trialkyl (or aralkyl)-substituted tetrahydropyrimidines (THP's) by reacting trialkyl (or aralkyl)-hexahydrotriazines and/or N,N'- dialkylidene 1,1- diamino alkanes in the presence of a Lewis acid; and to the products thereof.
