The work of Lee, Song and coworkers (1) provides an versatile route to symmetrical and unsymmetrical diarylalkynes. Their method is complementary to the powerful Sonagashira coupling of aryl halides and alkynes, and offers an alternative to the established ways to make diarylalkynes.

Our second set of evaluations was guided by the work of Bahrami, Khodaei, and coworkers (1). Their sulfide oxidation method seemed attractive for our purposes, and there were several examples given which were structurally similar to our target compounds. The oxidation procedure of Bahrami, Khodaei

The sulfide oxidation procedure of Page and coworkers (1) Our first trial was based on the work of  Page and coworkers at the University of Liverpool (1). A first look at this procedure suggested it would be simple to implement in the lab and could be

The lab recently required some small (5-10g) samples of some simple dialkyl sulfoxides. This led us to investigate dialkylsulfide oxidation procedures capable of  producing these compounds selectively, with minimal overoxidation to sulfone byproducts. There are, of course, many ways to go about this reaction. Hydrogen
