A simplified method for the preparation of ethynyl P-tolyl sulfone and ethynyl phenyl sulfone

Article abstract of DOI:10.1080/00397919408011330

Silica gel mediated desilylation of aryl 2-(trimethylsilyl)ethynyl sulfones was found to greatly simplify the synthesis of the acetylenic sulfones, ethynyl p-tolyl sulfone 1 and ethynyl phenyl sulfone 2. Each were easily prepared in good yield and high purity on a multigram scale from bis(trimethylsilyl)acetylene 3.
