摘要

The IR spectra of ethyl 4, 4, 4-trifluoroacetoacetate, ethyl 4, 4-difluoroacetoacetate and ethyl 4-fluoroacetoacetate, their enol acetates and trifluoroacetates, and their copper chelates are compared with those of ethyl acetoacetate and its corresponding derivatives. The marked influence of neighboring fluorine atoms on the characteristics frequencies associated with such structures is noted. Related data on enol acetates of β-diketones is also presented. ...
