5-propyl-2-((trityloxy)methyl)thiophene-3-carbaldehyde was synthesized by using the concept of chemo- and regioselective Br/Li exchange reaction from 3-bromo-5-propyl-2-((trityloxy)methyl)thiophene. This is a five-step protocol starting from thiophene with an overall yield of 33%. These lithium/halogen exchange reactions were carried out at −78 °C to rt over the period of 1 to 18 h depending on the reactivity of electrophiles.

The thiophosphonic and thiophosphinic halides, C6F5P(S)X2, (C6F5)2P(S)X, and R(C6F5)P(S)X (X = F, Cl, Br, and R = CH3, C2H5, tert-C4H9, C6H5) have been prepared, a) by addition of sulfur to the phosphorus(III) derivatives, b) by the reaction of chlorophosphoranes with H2S, and c) by halogen exchange reaction. The 31P- and 11F NMR data are discussed.
