Exploring bis-(amino)cyclopropenylidene as a non-covalent Brønsted base catalyst in conjugate addition reactions
Literature Information
Gurdeep Singh, Prithwish Goswami, Ramasamy Vijaya Anand
Bis-(amino)cyclopropenylidene has been utilised as a non-covalent Brønsted base catalyst in the 1,6-conjugate addition of carbon nucleophiles to p-QMs. This protocol makes it possible to access unsymmetrical diaryl- and triarylmethanes in good to excellent yields. Further, this catalyst was also explored in the 1,4-conjugate addition of carbon nucleophiles to enone systems.

Organic & Biomolecular Chemistry

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
