An electrochem. dearomatizing spirocyclization of alkynes with di-Me 2-benzylmalonates for the preparation of spiro[4.5]deca-trienones had been developed. This approach adopted ferrocene (Cp2Fe) as an electrocatalyst to produce carbon-centered radical intermediates from C-H-based malonates, which obviated the forthputting of noble-metal reagents, sacrificial chem. oxidants and 2-bromomalonates. A wide variety of spiro compounds were efficiently prepared with satisfactory results under mild conditions. In the experiment, the researchers used many compounds, for example, 2-Ethynylthiophene (cas: 4298-52-6HPLC of Formula: 4298-52-6).
2-Ethynylthiophene (cas: 4298-52-6) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.HPLC of Formula: 4298-52-6
