Synthesis of Silica Iodide as a New Heterogeneous Reagent and its Application to Conversion of Alcohols to Alkyl Iodides

A simple and mild procedure, which takes only a short time at room temperature and gives a high yield for conversion of alcohols to alkyl iodides using silica iodide as a new heterogeneous reagent is described. Silica-iodide is synthesized from the reaction between silica gel, triphenylphosphine, and iodine in dichloromethane solvent. The amount of iodide loaded on silica gel is ۰.۵ mmol/g. The conversion of alcohols to the corresponding alkyl iodides is carried out in ۵ minutes at room temperature with a yields between ۱۲-۹۹%.
