General Description

Dimethyl dodecanedioate, also known as dimethyl dodecanedioate, is a chemical compound with the molecular formula C14H26O4. It is an ester, derived from the condensation of dodecanedioic acid and methanol. This chemical is commonly used as a fragrance ingredient in perfumes and personal care products due to its pleasant fruity and floral odor. It is also used as a flavoring agent in food products and as a solvent in various industrial applications. Dimethyl dodecanedioate is considered safe for use in these applications when used in accordance with the regulations and guidelines set by the relevant authorities.

Polymerisable di- and triesters from Tall Oil Fatty Acids and related compounds

Tall Oil Fatty Acids, a low value side product from the paper industry containing mainly oleic and linoleic acids, are used for producing the polyester precursor, dimethyl 1,19-nonadecanedioate by methoxycarbonylation in the presence of [Pd2(dba)3], 1,2- bis(ditertiarybutylphosphinomethyl)benzene and methanesulfonic acid in methanol. The methoxycarbonylation of methyl linoleate has been used to identify other products formed and approaches to their minimisation have been developed. It has also been used for the production of trimethyl heptadecanetricarboxylates. Finally, conjugated unsaturated esters of different chain length (up to 16 C atoms), some of them available from plant oils, are subjected to methoxycarbonylation to give α,ω-diesters.

Development of efficient palladium catalysts for alkoxycarbonylation of alkenes

Herein, we report a general and efficient Pd-catalysed alkoxycarbonylation of sterically hindered and demanding olefins including a variety of tri-, tetra-substituted and 1,1-disubstituted alkenes. In the presence of 1,3-bis(tert-butyl(pyridin-2-yl)phosphanyl)propane L3 or 1,4-bis(tert-butyl(pyridin-2-yl)phosphanyl)butane L4 the desired esters are obtained in good yields and selectivities. Similar transformation is obtained using tertiary ether as showcased in the carbonylation of MTBE to the corresponding linear ester in high yield and selectivity.
