1-ETHYNYL-2-FLUOROBENZENE Usage And Synthesis

Chemical Properties

clear yellow to brownish liquid

Uses

Employed in studies on the polymerization1 and cross-coupling2 of phenylacetylenes.

Uses

1-Ethynyl-2-fluorobenzene has been employed in the cross-coupling of phenylacetylenes. It may be used in the preparation of 3-(2-deoxy-β-D-ribofuranosyl)-6-(2-fluorophenyl)-2,3-dihydrofuro-[2,3-d]pyrimidin-2-one and 4-(2-fluorophenylethynyl)-3-methyl-5-phenylisoxazole.

Application

1-Ethynyl-2-fluorobenzene has been employed in the cross-coupling of phenylacetylenes. It may be used in the preparation of 3-(2-deoxy-β-D-ribofuranosyl)-6-(2-fluorophenyl)-2,3-dihydrofuro-[2,3-d]pyrimidin-2-one and 4-(2-fluorophenylethynyl)-3-methyl-5-phenylisoxazole.1-Ethynyl-2-fluorobenzene, a fluorinated benzene derivative, is a terminal alkyne.

General Description

1-Ethynyl-2-fluorobenzene, a fluorinated benzene derivative, is a terminal alkyne.
