Microwave-assisted Intramolecular Dehydrogenative Diels-Alder Reactions for the Synthesis of Functionalized Naphthalenes/Solvatochromic Dyes

The overall goal of the following experiment is to generate functionalized napoles via a microwave assisted dehydrogenate dehydro ideals alder or DDDA reaction. This is achieved by microwave irradiation of styre precursors to produce diverse lene substrates. As a second step, a buckwald hardwig palladium catalyzed cross coupling reaction of the hynes with an amine is conducted.

This results in naphthalene containing electron donating and electron withdrawing groups that function as slv chromic fluorescent dyes, and are structurally related to a commercially available dye pro. Dan next solutions of the dye are prepared in order to measure the selected photo physical properties of the new substrates. This novel synthetic approach affords access to molecular architectures, possessing desirable photo, physical properties, and attractive chemical properties.
