Detailed explanation-1: -Decarboxylation reaction is defined as a chemical reaction that eliminates a carboxyl group and liberates carbon dioxide (CO2). Decarboxylation mostly refers to a reaction of carboxylic acids erasing a carbon atom from a chain of carbons.

Detailed explanation-2: -Loss of carbon dioxide is called decarboxylation. Esters or carboxylic acids with a carbonyl group at the 3-(or b-) position readily undergo thermal decarboxylation. Decarboxylation was first encountered in Chapter 19 for carboxylic acids (review). The reactive species is the carboxylic acid or the carboxylate anion.

Detailed explanation-3: -Oxidative decarboxylation is a decarboxylation reaction caused by oxidation. Most are accompanied by -Ketoglutarate -Decarboxylation caused by dehydrogenation of hydroxyl carboxylic acids such as carbonyl carboxylic acid, malic acid, isocitric acid, etc.

Detailed explanation-4: -With strong heating, formic acid and some of its derivatives may undergo decarbonylation, even without adding a catalyst. For instance, dimethylformamide ((CH 3) 2NC(O)H) slowly decomposes to give dimethylamine and carbon monoxide when heated to its boiling point (154 °C).
