A geminal interaction in the iodination of methoxyacetone
Abstract
Iodination of methoxyacetone yields initially 1-iodo-3-methoxypropanone, which then rearranges to its 1,1-isomer; the latter product is favoured thermodynamically by a factor of 2.9 × 105 as a result of a stabilising interaction between geminal iodine and oxygen atoms.
