The subsequent dehydration of the selected phosphonates and phosphinates proceeds smoothly affording previously unknown diethyl 1,2-unsaturated 1-trifluoromethyl-3-oxophosphonates, ethyl 1-trifluoromethyl-3-oxo(methyl)-, and ethyl 1-trifluoromethyl-3-oxo(phenyl) phosphinates in good yields Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Chizhov, D.
