Studies of fluorinated β-diketones and related compounds. Part II. Synthetic and infrared spectral studies of 1,3-diketonatochromium derivatives, and their substitution reactions

Abstract

Seventeen 1,3-diketonatochromium derivatives have been prepared from fluorinated β-diketones, and their electrophilic substitution reactions have been studied. Chloro-, bromo-, and nitro-substituents have been introduced at the central carbon atom of the ligand under controlled conditions. The effect of these groups on CO and CC stretching frequencies is discussed.
