What is 9-Dioctylfluorene-2 7-bis(boronic acid pinacol ester?

     With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 9,9-Dioctylfluorene-2 7-bis(boronic acid pinacol ester which has developed particularly rapidly in recent years. Do you know about 9,9-Dioctylfluorene-2 7-bis(boronic acid pinacol ester?

The official answer: United boronic acid pinacol ester is in the form of a white to off-white powder and is used mainly in organic synthesis. Reagent for the cis-linked boronisation of acetylene and paraffin (platinum-catalyzed); palladium-catalyzed boronisation of aromatic compounds. Substrate in the palladium-catalyzed cyclisation of 1,6-enyne to homoallylic alkylboronates.

What’s the application of 9-Dioctylfluorene-2 7-bis(boronic acid pinacol ester?

For the construction of tetramethylpyrrolidine nitroxide scaffolds for the synthesis of paramagnetic heterocyclic compounds via Suzuki coupling reactions; for platinum-catalyzed acetylene and olefin cis-Chemicalbook o-diborylation reactions; for palladium-catalyzed borylation reactions of aromatic hydrocarbons; as a substrate for a novel palladium-catalyzed cyclization of 1,6-enyne to produce higher allyl alkyl boronic esters. Obtained by reduction from acetone. Magnesium chips are put into industrial benzene, heated at reflux, and a solution of acetone and mercuric chloride is slowly added to the reaction for 2 h. After the reaction, the benzene is cooled and filtered to recover the benzene, and then water is added to Chemicalbook, and the pinacol crystals containing water of crystallization come out.
