What are anhydride linkages?
Acid anhydrides are reactive and are good acylating agents. The two terminal phosphate linkages in ATP are anhydride linkages, and acid anhydrides play important roles in bioenergetics (see Adenylate Charge). Acid anhydrides are widely employed for chemical modification of proteins, particularly of amino groups.
What is the structure for acid anhydride?
An acid anhydride is a compound that has two acyl groups bonded to the same oxygen atom. A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride being (RC(O))2O.

Which is a conjugate acid of pivalic acid?
Pivalic acid is a branched, short-chain fatty acid composed of propanoic acid having two methyl substituents at the 2-position. It is a branched-chain saturated fatty acid, a methyl-branched fatty acid and a short-chain fatty acid. It is a conjugate acid of a pivalate. 2,2-dimethylpropanoic acid
How is pivalic acid used in organic synthesis?
Pivalic acid is employed as co-catalyst in some of the Palladium catalyzed C-H functionalization reaction. The pivaloyl group is used as a protecting group in organic synthesis.
Which is the best way to protect pivalic acid?
Common protection methods include treatment of alcohol with pivaloyl chloride (PvCl) in presence of pyridine. Alternatively, the esters can be prepared using pivaloic anhydride in the presence of scandium triflate (Sc (OTf) 3) or vanadyl triflate (VO (OTf) 2 ). Common deprotection methods involve hydrolysis with a base or other nucleophiles.
What is the neutral pH of pivalic acid?
The 1 H NMR spectrum at 25 °C and neutral pH is a singlet at 1.08 ppm. Pivalic acid is employed as co-catalyst in some of the Palladium catalyzed C-H functionalization reaction.
