crystallography. A preference for the formation of thermodynamic N2 isomers was established. Direct evidence of interconversion between N1- and N2-acyltriazoles confirmed their value in denitrogenative transformations. Efficient synthesis of enamido triflates from NH-triazoles via the intermediacy of N2-acyl-1,2,3-triazoles was developed.
通过直接酰化NH -
1,2,3-三唑形成的难以捉摸的 N-酰基-
1,2,3-三唑被分离出来并进行了充分表征,包括 X 射线晶体学。建立了热力学N 2 异构体形成的偏好。N 1- 和N 2- 酰基三唑之间相互转化的直接证据证实了它们在脱氮转化中的价值。开发了通过N 2-酰基-
1,2,3-三唑为中间体,从 NH-三唑高效合成烯酰胺
