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.I2 generated in situ from Fe(NO3)3·9H2O/NaI also catalyzed the formylation of the alcohols under solvent-free conditions.This gives a green and efficient reaction at room temperature,in which the use of toxic and corrosive molecular I2 is avoided. 展开更多
