Triethyl citrate is a colorless, odorless ester of citric acid. It is commonly used as a food additive and plasticizer in various products such as pharmaceuticals, food packaging, and personal care products due to its non-toxic and biodegradable nature.

The reaction mechanism involves the Lewis acid-catalyzed acylation of ferrocene with triethyl orthoformate in the presence of AlCl3. The AlCl3 activates the triethyl orthoformate to form an acylating agent, which then reacts with ferrocene to form formyl ferrocene. The aluminum chloride serves as a catalyst by facilitating the acylation process.

Citrate is the salt, an ester of citric acid, and the polyatomic anion that is found in solution. The ester can be triethyl citrate and the salt can be a trisodium citrate.

Triethyl phosphite reacts with aldehydes to form β-hydroxy phosphonates via a Pudovik reaction. This reaction involves the addition of the phosphite to the carbonyl group of the aldehyde, followed by a dehydration step to yield the β-hydroxy phosphonate product.
