14-Bis(Diphenylphosphino)Butane 98.0%(GC)

13-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields. 4-Ethynylanisole was used in the synthesis of photoluminescent 12-dihydrophosphinines via a [4 2] cycloaddition along with an arylboronic acid and sodium azide in a copper-catalyzed three-component synthesis of trisubstituted 124-triazoles in a study of a gold (III)-catalyzed hydroamination of alkynes leading to N-vinylindoles.

4-Ethynylanisole forms the corresponding propargyl aldehyde in good yield directly from DMF-dimethyl acetal without the need for making an acetylide salt. 13-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields
