Abstract
Acetylferrocene oxime was dilithiated with excess lithium diisopropyla mide and the resulting C(alpha),O-dilithiated oxime was condensed at t he carbanion-type center with aromatic esters to yield C-acylated inte rmediates that were quenched and acid-cyclized to the (5-aryl-3-isoxaz olyl)-ferrocenes (isoxazolyl-ferrocenes). The resulting products were isolated-in yields ranging from 20-76% and purified by recrystallizati on from ethanol.
