Piccialli, Vincenzo published the artcileBromination and iodination of donor-acceptor cyclopropanes. Evidence for an ET mechanism, Formula: C5H5ClIN, the publication is Tetrahedron Letters (2002), 43(45), 8067-8070, database is CAplus.
Et 2,2-dimethoxycyclopropanecarboxylates 1a-d react easily with Br2 and I2 in CCl4 or CH2Cl2 leading, in high yields, to 1-ethyl- or 4-methyl-2-halobutanedioates 2 and 3, resp. Bromination in the presence of pyridine, NBS, tri-Me phosphate, and iodination with ICl and ICl/pyridine was also performed. A common SET mechanism may be proposed for both halogenations; depending on the reaction conditions, bromination can also occur via acid-catalyzed or SE2 routes. The reaction of the 2-ethoxy analogs cis-12 and trans-12 with the same halogens proceeds in a similar manner, giving 3-formyl-2-halo esters along with the corresponding diethylacetals as main products. Iodination of 12 with the catalytic system NaI/m-CPBA/18-crown-6 also was studied.
Tetrahedron Letters published new progress about 6443-90-9. 6443-90-9 belongs to iodides-buliding-blocks, auxiliary class Pyridines, name is Pyridine Iodochloride complex, and the molecular formula is C5H5ClIN, Formula: C5H5ClIN.
