The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1-(Bromomethyl)-2-iodobenzene(SMILESS: BrCC1=C(I)C=CC=C1,cas:40400-13-3) is researched.Synthetic Route of C4H7BrO2. The article 《Effect of noncovalent interactions in ion pairs on hypervalent iodines: inversion of regioselectivity in sulfonyloxylactonization》 in relation to this compound, is published in Organic Chemistry Frontiers. Let’s take a look at the latest research on this compound (cas:40400-13-3).
Novel hypervalent iodines possessing cationic heterocyclic moieties nearby the iodine(III) center was synthesized. The novel hypervalent iodines exhibited a totally different regioselectivity from common PhI(OAc)2 during the sulfonyloxylactonization of 2-vinylbenzoic acids. The noncovalent interactions between the sulfonyloxy groups and the cationic heterocyclic moieties resulted in a significant change in the regioselectivity, which was revealed by the observation of intermediates and d. functional theory studies including noncovalent interaction anal.
