Copper-catalyzed coupling reaction of unactivated secondary alkyl iodides with alkyl Grignard reagents in the presence of 1,3-butadiene as an effective additive
Cu-catalyzed cross-coupling of unactivated secondary alkyl iodides with alkylGrignardreagents in the presence of 1,3-butadiene as a ligand precursor was developed. The use of 1,3-butadiene resulted in improved yields of alkyl-alkyl products with improved selectivities.
The invention is related to anti-viral compounds, compositions containing such compounds, and therapeutic methods that include the administration of such compounds, as well as to processes and intermediates useful for preparing such compounds.
alkoxycarbonylation of alkyl iodides with phenols and ethers. Based on the electron donor-acceptor photoactivation strategy, the reaction can be realized at atmospheric pressure of CO under transition metal-free conditions. This promising approach demonstrates high functional group tolerance and excellent chemoselectivity. Additionally, five-component perfluoroalkylative carbonylation for the synthesis of β-perfluoroalkyl
电荷转移络合物和光照射的结合为可持续化学的要求提供了一个有前途的解决方案。在此,我们开发了膦催化的可见光诱导的烷基碘与酚类和醚类的烷氧基羰基化反应。基于电子供体-受体光活化策略,该反应可以在无过渡金属的条件下在常压 CO 下实现。这种有前途的方法展示了高官能团耐受性和出色的化学选择性。此外,还可以实现由未活化的烯烃和全氟烷基碘化物合成β-全氟烷基酰氧基酯的五组分全氟烷基化羰基化反应。此外,由于克级反应的优异性能和13CO结果,它为大规模生产和其他应用提供了潜在的机会。
