Direct Alkynylation of Carbonyl Compounds Using an Efficient Catalytic System: Triisopropylsilanol/KOH
This project was supported by the National Natural Science Foundation of China (21202031) and the Natural Science Foundation of Zhejiang Province (Y4110297).

Abstract
The first triisopropylsilanol/KOH-catalyzed direct alkynylation of carbonyl compounds to access propargylic alcohols was achieved. This approach is particularly simple and operates under mild conditions. Moreover, the catalytic system exhibits a wide tolerance for various substrates, including aromatic aldehydes and aromatic acetylenes, giving 1,3-diarylpropargyl alcohols with yields exceeding 88%, avoiding the usual formation of chalcone derivatives or polymers.
