During the Diploma work I carried out reactions under solvent free conditions. From different ketones and phenylacetylene and in the presence of potassium tert-butoxide, I synthesized propargyl alcohols with good yields and at room temperature, with grinding in the mortar. I isolated the products with extraction and solvent distillation. Then I analyzed the products with 1H NMR spectroscopy. Spectra were recorded in CDCl3 at 300 MHz.
