Abstract
Alkyl arsines are made by a reaction of gaseous arsine and the corresponding gaseous olefin in contact with at least one Bronsted acid catalyst. Products produced thereby are mono- and di-substituted arsines, e.g. alkyl and di-alkyl arsines, which contain substantially no metallic or oxygenating impurities.
