4-Ethynylanisole

Pale Yellow Oil

1,3-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields.1

Intermediate in the synthesis of histamine H3-receptor antagonists. Also utilized to prepare its luminescent copper complex

4-Ethynylanisole was used in the synthesis of photo luminescent 1,2-dihydrophosphinines via a [4 + 2] cycloaddition. Along with an arylboronic acid and sodium azide in a copper-catalyzed, three-component synthesis of trisubstituted 1,2,4-triazoles. In a study of a gold (III)-catalyzed hydroamination of alkynes leading to N-vinylindoles3.

4-Ethynylanisole forms the corresponding propargyl aldehyde in good yield directly from DMF-dimethyl acetal without the need for making an acetylide salt. 1,3-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields.
