title: A new route for generation of alpha-lambda3-iodanyl ketones via ester exchange of (Z)-(beta-acetoxyvinyl)-lambda3-iodanes: their nucleophilic substitutions with halides and sulfur and phosphorus nucleophiles.
abstract: An efficient method for generation of alpha-lambda3-iodanyl ketones from (Z)-(2-acetoxyvinyl)(phenyl)-lambda3-iodanes was developed. The method involves ester exchange of (Z)-2-acetoxyvinyl-lambda3-iodanes with methanol in the presence of triethylamine. alpha-lambda3-Iodanyl ketones react with a variety of nucleophiles such as halides, thiols, phosphines, phosphinic acids, and phosphates, under the conditions which produce alpha-functionalized carbonyl compounds probably via an S(N)2 pathway.
