Application 1,3-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields.1 Forms the corresponding propargyl aldehyde in good yield directly from DMF-dimethyl acetal without the need for making an acetylide salt. Used together with an arylboronic acid and sodium azide in a copper-catalyzed, three-component synthesis of trisubstituted 1,2,4-triazoles. Employed in a study of a gold (III)-catalyzed hydroamination of alkynes leading to N-vinylindoles. Packaging 1, 5 g in glass bottle
