  α-Alkylation of methyldiarylphosphine oxides with (hetero)arylmethyl alcohols was performed under nickel catalysis. Various arylmethyl and heteroarylmethyl alcohols can be used in this transformation. A series of methyldiarylphosphine oxides were alkylated with 30–90% yields. Functional groups on the aromatic rings of methyldiarylphosphine oxides or arylmethyl alcohols including OMe, NMe2, SMe, CF3, Cl, and

• Rh-Catalyzed Negishi Alkyl-Aryl Cross-Coupling Leading to α- or β-Phosphoryl-Substituted Alkylarenes

  The catalytic cross-coupling between ArZnX and ICH2(CH2)(n)P(O)(OEt)(2) (n = 0-3) has been investigated to determine the utility of the Rh catalyst during the alkyl-aryl cross-coupling and to develop a new synthetic method for phosphoryl-substituted alkylarenes. Rh-dppf exhibits an excellent catalytic activity for the reaction with the alkylphosphonate of n = 1, whereas for the reaction with those of n = 2 or 3, P-hydride elimination mainly takes place. As for the reaction with an alkylphosphonate of n = 0, a polarity inversion of the coupling components is necessary in order to provide the coupling products; the phosphoryl analogue of the Reformatsky reagent and ArI give the cross-coupling products in good yields through the catalysis by Rh-dppf.
• A Novel Synthesis of Phosphonates from Diethyl (Trichloromethyl)phosphonate

  日期：1994.8

  Commercially available diethyl (1,1,1-trichloromethyl)phosphonate was reacted with aldehydes and ketones to generate (chlorovinyl)phosphonates in a single step. These intermediates could be hydrogenated in high yields to the corresponding saturated phosphonates.
