Article abstract of DOI:10.1055/s-1988-27731

Reaction of I(collidine)2(1+) ClO4(1-) with unsaturated alcohols and carboxylic acids in dichloromethane at ambient temperature has afforded three- to seven-membered-ring iodoethers and four- to seven-membered-ring iodolactones, respectively, in moderate
