ortho- and meta-Selective C-H Activation and Borylation of Aromatic Aldehydes via in situ Generated Imines was written by Bisht, Ranjana;Chattopadhyay, Buddhadeb. And the article was included in Synlett in 2016.Formula: C14H19BO4 The following contents are mentioned in the article:
A ligand-controlled discovery of ortho and meta C-H borylation of aromatic aldehydes is described. In both cases, an amine is used and it was proposed that ortho borylation could be realized using tert-butylamine as the traceless protecting/directing group and meta borylation undergoes via an electrostatic interaction and a secondary interaction between the ligand of the iridium catalyst and the substrate. Remarkably, these electrostatic interactions and secondary B-N interactions offer a unique and unprecedented guiding factor for the meta-selective C-H activation/borylation of benzaldehydes. This is the first example for the C-H activation and functionalization where the ortho and meta position of a substrate has selectively been functionalized, which open a new chapter in electrophilic aromatic substitution. 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: 1132669-90-9Formula: C14H19BO4).
5-Methoxy-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (cas: 1132669-90-9) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Formula: C14H19BO4
