Bis(2,2,2-trifluoroethyl) Carbonate as a Condensing Agent in One-Pot Parallel Synthesis of Unsymmetrical Aliphatic Ureas
摘要:
One-pot parallel synthesis of unsymmetrical aliphatic ureas was achieved with bis(2,2,2-trifluoroethyl) carbonate. The procedure worked well for both the monosubstituted and functionalized alkyl amines and required no special conditions (temperature control, order, or rate of addition). A library of 96 diverse ureas was easily synthesized.

A triazine derivative represented by the general formula:
wherein R1 and R2 are each an alkyl group having 1 to 4 carbon atoms, and X1 and X2 are each a halogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxyl group having 1 to 4 carbon atoms, or an alkylthio group having 1 to 4 carbon atoms.
This invention also provides a process for efficiently preparing said triazine derivative and a herbicide containing said triazine derivative as effective component.
