Synthesis of bis(indolyl)methanes using N-heterocyclic carbene salt as a C1 precursor
We herein describe an alkylation reaction of indoles with NHC salts to access bis(indolyl)methanes as product. The NHC salt (or free NHC) serves as a C1 precursor due to decomposition of its N-heterocyclic ring. Although the exact roles of zinc powder and acetic/formic acid remain elusive, both of t...
