with Me3SiCl–LiAlH4 gives the air-stable primary phosphines FcCH2CH2PH2 and the previously reported analogue FcCH2PH2 in high yields. Reduction of 1,1′-Fc′[CH2P(O)(OEt)2] [Fc′=Fe(η5-C5H4)2] and 1,2-Fc″[CH2P(O)(OEt)2] [Fc″=Fe(η5-C5H5)(η5-C5H3)] similarly gives the new primary phosphines 1,1′-Fc′(CH2PH2)2 and 1,2-Fc″(CH2PH2)2, respectively. The arsine FcCH2CH2AsH2, which is also air-stable, has been
A new approach is proposed for ferrocene phosphorylation using α-hydroxylalkylphosphonate as a “masked” phosphorylating agent, by electrochemical reduction of a ferrocene and (Me)2C(OH)P(O)(OC2H5)2mixture at −50 °C.
