| Abstract: | A series of novel 3,4 difluorothiophenol ester compounds have been synthesized with yield from 64.2% to 74.9%. All of these compounds are identified by IR and 1H NMR. The effects of solution on the selectivity of acylation are also been studied. The results of thermal analysis show that these compounds have broad nematic phase range and high clearing point. |
