In this study, we developed a rhodium(I)-catalyzed spirocyclization. The reaction includes 1,4-rhodium migration and provides a route for forming spirocyclic 1-indanones. This study involved multiple reactions and reactants, such as 5-Methoxy-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (cas: 1132669-90-9Electric Literature of C14H19BO4).
5-Methoxy-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (cas: 1132669-90-9) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Electric Literature of C14H19BO4
