Usage

General Description

2-Methylundecanal dimethylacetal is a chemical compound that belongs to the class of dimethylacetals. It is derived from the aldehyde 2-methylundecanal, which is a long-chain aldehyde with a distinct odor. The dimethylacetal form is a colorless liquid with a sweet, floral odor but can also be used as a flavoring agent in various products. It is commonly used in the fragrance and flavor industry due to its pleasant scent and is often found in perfumes, soaps, and other personal care products. Additionally, it has potential applications as a flavoring agent in the food industry.

Highly effective tandem hydroformylation-acetalization of olefins using a long-life Bronsted acid-Rh bifunctional catalyst in ionic liquid-alcohol systems

A robust and highly effective tandem hydroformylation-acetalization of olefins using a Bronsted acid-Rh bifunctional catalyst (ARBC) in ionic liquid-alcohol systems is reported. The key feature of the ARBC is its use of a zwitterionic phosphine ligand bearing an amino acid tag. This novel ARBC shows an excellent catalytic efficiency and a long service life without a significant drop in both the hydroformylation efficiency and the acetalization efficiency or Rh loss for more than seventeen cycles. We believe that the long-term high activity and acetal selectivity mainly benefit from the synergy between the acidic active site and the Rh active site on the ARBC and the highly effective immobilization and recycling of ARBC in ionic liquid-alcohol systems due to the strong affinity of ARBC for the ionic liquid.

Functional transformation of aldehydes and ketones via homolytic induced decomposition of unsaturated peroxy acetals and peroxy ketals

Induced decomposition of unsaturated peroxy acetals prepared from trimethyl orthoformate, dodecanal or 2-methyl-undecanal and 2,3-dimethyl-2-hydroperoxybut-3-ene, in the presence of ethyl iodoacetate, CC14 or dodecanethiol, allowed respectively their iodo-, chloro- and hydro-decarbonylation with yields of over 70%; the same reaction applied to the monoperoxy ketal or diperoxy ketal of cyclohexanone in the presence of ethyl iodoacetate resulted in its functional transformation in methyl 6-iodohexanoate or 1,5-diiodopentane with respective yields of 65 and 40%.
