Cyclopropane Reaction Mechanisms

Cyclopropane Reaction Mechanisms is a research topic within Organic Chemistry. Science Explorer counts 29k research works in it since 1950. 19.1% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the catalytic carbene chemistry in organic synthesis, particularly on the use of donor-acceptor cyclopropanes, diazo compounds, and metal-catalyzed reactions. It covers topics such as enantioselective synthesis, site-selective functionalization, and the development of artificial metalloenzymes for carbene transfer reactions.
