Similarly it gives boronic acid esters, which can be useful in the cross coupling reactions. [3] [4] A condensation reaction of neopentyl glycol with 2,6-di-tert-butylphenol gives CGP-7930. Neopentyl glycol is a precursor to Neopentyl glycol diglycidyl ether. The sequence begins with alkylation with epichlorohydrin using a Lewis acid catalyst.
Phenylboronic acid or benzeneboronic acid, abbreviated as PhB(OH) 2 where Ph is the phenyl group C 6 H 5 - and B(OH) 2 is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Phenylboronic acid is a white powder and is commonly used in organic synthesis.
4-Formylphenyl boronic acid crystallizes in colorless needles [1] or is obtained as an odorless, whitish powder, which dissolves little in cold but better in hot water. The compound is quite stable [3] and readily forms dimers and cyclic trimeric anhydrides, which complicate purification and tend to protodeboronize, a secondary reaction that occurs frequently in the Suzuki coupling, with ...
The mechanism of organotrifluoroborate-based Suzuki-Miyaura coupling reactions has recently been investigated in detail. The organotrifluoroborate hydrolyses to the corresponding boronic acid in situ, so a boronic acid can be used in place of an organotrifluoroborate, as long as it is added slowly and carefully.

Dibromo neopentyl glycol diglycidyl ether is a brominated version of neopentyl glycol diglycidyl ether. It is an aliphatic organic chemical in the glycidyl ether family that is used in epoxy resin formulations. It has the molecular formula C 11 H 18 Br 2 O 4
4-Fluorophenibut (developmental code name CGP-11130; also known as β-(4-fluorophenyl)-γ-aminobutyric acid or β-(4-fluorophenyl)-GABA) is a GABA B receptor agonist which was never marketed. [1] It is selective for the GABA B receptor over the GABA A receptor ( IC 50 = 1.70 μM and > 100 μM, respectively). [ 1 ]
Tetrafluorophenyl (TFP) ester chemistry is typically used to attach fluorophores or haptens to the primary amines of biomolecules. They produce the same amide bonds that are formed through conjugation with other amine-reactive groups, such as succinimidyl esters (SE, Hydroxysuccinimide- or NHS-ester), but TFP esters are less susceptible to spontaneous hydrolysis during conjugation reactions.
Pentafluorophenyl (PFP) esters are chemical compounds with the generic formula RC(O)OC 6 F 5. They are active esters derived from pentafluorophenol (HOC 6 F 5 ). PFP esters are useful for attaching fluorophores such as fluorescein [ 1 ] or haptens [ 2 ] to primary amines in biomolecules.
