Reaction of carbanions generated from arylmethylphosphonates with cyclic enones. Regio- and stereoselectivity of addiction
alpha-Lithiated benzylphosphonate esters, XC6H4CH(Li)PO3Et2, add regioselectively to cyclohex-2-enone at the carbonyl group; higher reaction temperatures lead to the reversal to the starting materials, and not to the 1,4-addition.
