showing that the C2F5‐ligated Cu atom can be di‐ (5), tri‐ (2 and 3), and tetracoordinate (4). The mixed phen‐PPh3 complex 4 is a highly efficient fluoroalkylating agent for a broad variety of acid chlorides. This high‐yielding transformation represents the first general method for the synthesis of RCOC2F5 from the corresponding RCOCl.
制备了四个带有C 2 F 5配体的定义明确的Cu I络合物,并对其进行了全面表征:[(Ph 3 P)2 CuC 2 F 5 ](2),[(bpy)CuC 2 F 5 ](3) ,[(Ph 3 P)Cu(phen)C 2 F 5 ](4)和[(IPr *)CuC 2 F 5 ](5)。确定了全部四个的X射线结构,表明C 2 F 5连接的Cu原子可以是二(5),三(2和3)和四坐标(4)。混合的phen-PPh 3络合物4是一种高效的氟代烷基化剂,适用于多种酰氯。这种高产的转化代表了从相应的RCOCl合成RCOC 2 F 5的第一种通用方法。
