摘要

New sterically hindered ferrocenyl containing phosphonium salt was synthesized in two steps starting from ferrocene. To avoid halogen contamination di-tert-butylferrocenylphosphine was quaternized with methyl bis(trifluoromethanesulfonyl)imide directly. Obtained phosphonium salt was characterized with several physical methods. [GRAPHICS] .
