In this study, the synthesis of gem-dialkyl cyclopropanes using in situ-generated dialkyl diazo compounds under Bamford-Stevens conditions is reported. A simple cobalt catalyst was found to be the optimal choice for achieving high yields. Experimental and computational studies suggest the involvement of a metalloradical reaction mechanism, which enables carbene transfer reactions and provides a one-step access to dialkyl-substituted cyclopropanes.
The synthesis of dialkyl-substituted cyclopropanes is an important challenge in synthesis with applications in drug discovery and agrochemistry. Herein, we report on the synthesis of gem-dialkyl cyclopropanes with in situ-generated dialkyl diazo compounds under Bamford-Stevens conditions. A simple cobalt catalyst was identified to be optimal to achieve high yields. Experimental and computational studies suggest the participation of a metalloradical reaction mechanism that facilitates the carbene transfer reactions and provides access to dialkyl-substituted cyclopropanes in a single step.
