Metal-free phosphonation of benzoxazoles and benzothiazoles under oxidative conditions?
Organic Chemistry Frontiers Pub Date: 2017-06-05 DOI: 10.1039/C7QO00318H
Abstract
An iodine promoted phosphonation of benzoxazoles and benzothiazoles with trialkyl phosphites was described. This reaction undergoes three steps: an addition procedure, followed by a radical oxidation, and an elimination reaction, provides an efficient method to access 2-phosphated products with a broad scope of substrates.
