A hot couple: An unprecedented rhodium(III)‐catalyzed cross‐dehydrogenative coupling (CDC) of various furan and thiophene derivatives leads to valuable 2,2′‐bi(heteroaryl) products in good yields and selectivities (see scheme). In addition, pyrroles and indoles can also be used as coupling partners, giving C3‐arylated products.
热对偶:各种呋喃和噻吩衍生物在铑(III)催化下的前所未有的铑(III)催化的交叉脱氢偶联(CDC)导致了有价值的2,2'-双(杂芳基)产品,具有良好的收率和选择性(请参见方案)。此外,吡咯和吲哚也可以用作偶联剂,得到C3芳基化的产物。
