Abstract
'Y-Bromoacetoacetic ester and triethyl phosphite yield a mixture
of isomeric diethyl 2-keto-3-carbethoxypropyl-phosphonate (1) and
diethyl 1-carbethoxy-isopropen-2-yl-phosphate (2). The influence of
the reaction temperature on the formation of both compounds has
been investigated. Lower temperature increases the yield of (2)
and higher of (1). The compounds were separated by vacuum distillation
and were identified by elemental analysis, ir and 1H NMR
spectra.
