4-Ethynyltoluene (CAS: 766-97-2) was used in the synthesis of bis(bicyclic) products by the cycloaddition of alkynes to the AlN2C2. Intermediates of Liquid Crystals. A useful protecting group (Ph2P(O)) reagent for terminal ethynes for the synthesis of electronic devices. 4-Ethynyltoluene is an aryl-terminal alkyne compound. Aryl-terminal alkynes are important intermediates in organic synthesis. Polyaryl-terminal alkynes, polyaryl-dialkynes and conjugated macromolecules of aryl-terminal alkynes are not only used in drugs, pesticides and other aspects, but also in new organic functional materials and molecular electronic devices. Such as organic light-emitting diodes, liquid crystal materials, nonlinear optical materials, gas separation membrane, molecular wires, molecular switches, molecular computers and other fields have a wide range of application prospects.
