In the reaction of dimethyl sulfoxide with 2-furyl bromomethyl ketone (Ia), 5-nitro-2-furyl bromomethyl ketone (Ib), and 4-bromophenacyl bromide (Ic) at room temperature, methyl 2-furoylthiol formate (IIIa), methyl 5-nitro-2-furoylthiol formate (IIIb), and methyl 4-bromobenzoylthiol formate (IIIc) were newly isolated besides 2-furylglyoxal (IIa), 5-nitro-2-furylglyoxal (IIb), and 4-bromophenylglyoxal (IIc). Variation in the amounts of IIa, b, c and IIIa, b, c formed was examined by gas chromatography while varying the reaction temperature and time.
