Diethyl trichloromethylphosphonate, treated with BuLi
followed by an aldehyde (or cycloalkenone), was converted to
α-chlorovinylphosphonates via the intermediate
formation of a bisphosphonate and a WadsworthâEmmons
olefination. High (Z) stereoselectivity of the reaction is
discussed in terms of the conformational preferences of the
adducts.
