Cinnamic acid is an organic compound with the formula C 6 H 5-CH=CH-COOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. [ 4 ] Classified as an unsaturated carboxylic acid , it occurs naturally in a number of plants.
An example of such a reaction is one with the use of cinnamyl bromide 3 and sodium acetate as reactants. Since these compounds are immiscible substrates, solid-liquid phase transfer catalysis (PTC) can be used, using quaternary ammonium bromide as a phase transfer catalyst. This is shown in the following reaction: [19]

Methyl cinnamate is the methyl ester of cinnamic acid and is a white or transparent solid with a strong, aromatic odor. It is found naturally in a variety of plants, including in fruits, like strawberry, and some culinary spices, such as Sichuan pepper and some varieties of basil. [4]
Balsam of Peru contains 25 or so different substances, [6] including cinnamein, cinnamic acid, cinnamyl cinnamate, benzyl benzoate, benzoic acid, and vanillin. [7] [8] It also contains cinnamyl alcohol, cinnamaldehyde, farnesol, and nerolidol. [9] A minority of it, approximately 30–40%, contains resins or esters of unknown composition. [8]
Olefin metathesis has been widely studied. One of the synthesis pathways for octyl methoxycinnamate includes cross metathesis. The high efficiency of the nitro-Grela catalyst has been used in the cross metathesis of trans-anethole with 2-ethylhexyl acrylate to produce octyl methoxycinnamate (86% yield).
Ethyl cinnamate is the ester of cinnamic acid and ethanol. It is present in the essential oil of cinnamon. [citation needed] Pure ethyl cinnamate has a "fruity and balsamic odor, reminiscent of cinnamon with an amber note". [1] The p-methoxy derivative is reported to be a monoamine oxidase inhibitor. [2]
o-Coumaric acid is a hydroxycinnamic acid, an organic compound that is a hydroxy derivative of cinnamic acid. There are three isomers of coumaric acids — o -coumaric acid, m -coumaric acid, and p -coumaric acid — that differ by the position of the hydroxy substitution of the phenyl group.
