Abstract 1‐Butyl‐3‐methylimidazolium hydrogen sulfate [bmim]HSO 4 as an acidic ionic liquid was prepared and used as a catalyst for the formylation of alcohols with ethyl formate at room temperature with good to excellent yields. A good selectivity was observed for the formylation of primary alcohols in the presence of tertiary alcohols.
