, p. 1430 - 1434 (2010)
The catalytic application of p-toluenesulfonyl chloride for efficient acetylation of various types of alcohols and phenols with acetic anhydride in solvent-free conditions is reported. Also structurally diverse alcohols were formylated using formic acid based on the use of catalytic amount of p-toluenesulfonyl chloride under solvent-free condition. The reactions were carried out in short reaction time and in good to excellent yields at room temperature.

, p. 711 - 714 (1998)
The Vilsmeier reagents generated from tertiary and secondary aliphatic and aromatic amides and trifluoromethanesulfonic anhydride (Tf2O) reacted with different nucleophiles (ROH, RSH, RNH2) affording the relative iminium and amidinium salts. The former, stable at room temperature, were easily transformed into the corresponding esters or O-alkyl thioesters by treatment with OH- or SH-.
Formylation of alcohol with formic acid under solvent-free and neutral conditions catalyzed by free I2 or I2 generated in situ from Fe(NO3)3·9H2O/NaI

experimental part, p. 60 - 64 (2011/10/08)
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.
Silica-bonded N-propyl sulfamic acid as an efficient catalyst for the formylation and acetylation of alcohols and amines under heterogeneous conditions
Niknam, Khodabakhsh,Saberi, Dariush
experimental part, p. 5210 - 5214 (2009/12/06)
A simple and efficient procedure for the preparation of silica-bonded N-propyl sulfamic acid (SBNPSA) by the reaction of 3-aminopropylsilica (1) and chlorosulfonic acid in chloroform is described. This solid acid is employed as a new catalyst for the formylation of alcohols and amines with ethyl formate under mild and heterogeneous conditions at room temperature with good to excellent yields. Also, SBNPSA catalyzed acetylation of various alcohols and amines with acetic anhydride at room temperature.
