Abstract

Abstract : An air-stable, commercially available iron catalyst provides fast efficient double hydrophosphination of alkynes under thermal or photochemical conditions. Abstract : A commercially available iron compound, [CpFe(CO)2 ]2 (1 ) (Cp = η 5 -C5 H5 ), is an efficient catalyst for the double hydrophosphination of terminal aryl alkynes with diphenylphosphine under visible light irradiation or thermal conditions with a reduction of reaction times of up to two orders of magnitude for some substrates over literature reports. The 1, 2-bis(diphenylphosphino)ethane products generated in these reactions are readily isolated in high yields.
