Gold‐catalyzed functionalization of semicarbazides with various terminalalkynes grants a wide range of semicarbazones. Inspection of XRD solid‐state structures of the obtained semicarbazones proved their dimerization via weak to moderate strength hydrogen bonding. The nature and energy of this H‐bonding, degree of electron density delocalization, and rotational barriers of various bonds were studied
各种末端炔烃在金催化下的氨基脲官能团可得到各种氨基脲。对所获得的半咔唑的XRD固态结构的检查证明了它们是通过弱至中等强度的氢键形成二聚体的。在M06-2X / 6-311 ++ G **理论水平上通过DFT计算研究了这种H键的性质和能量,电子密度离域度以及各种键的旋转势垒。
