Different alcohols were formylated by formic acid under solvent-free conditions in the presence of iodine as the catalyst with good-to-high yields at room temperature. I 2 generated in situ from Fe(NO 3 ) 3 •9H 2 O/NaI also catalyzed the formylation of the alcohols under solvent-free conditions. Thi

## Abstract Structurally diverse alcohols and phenols were trimethylsilylated in a clean and efficient reaction with hexamethyldisilazane (HMDS) based on the use of I~2~ generated __in situ__ from Fe(NO~3~)~3~⋅9 H~2~O/NaI. The reaction occurs very rapid in good‐to‐high yield in CH~2~Cl~2~ at room t
