Usage

General Description

3,3'-dithiobis[2,5-dimethylfuran], also known as DTDMF, is a chemical compound with the molecular formula C12H14OS2. It is a sulfur-containing heterocyclic compound that is commonly used as a cross-linking agent in the production of rubber. DTDMF helps to improve the physical properties of rubber, such as its strength and durability, by creating cross-links between polymer chains. It is also used as a curing agent in the manufacturing of rubber products, such as tires and conveyor belts. Additionally, DTDMF has potential applications in the synthesis of pharmaceuticals and agrochemicals due to its unique structure and properties. However, it is important to handle DTDMF with caution as it may pose health and environmental risks if not properly managed.

182. Novel Access to Furan-3-thiols and Derivatives, Impact Meat-Flavor Compounds

A versatile process for the preparation of a number of 3-thio-substituted furans 1-4 is described.These products have very low odor thresholds and are thus potent flavor compounds.Fur-3-yl thiocyanates 10a,b as well as other S-containing analogues (2b, 7a, b, and 8) were prepared by a Michael-type addition of thiocyanic acid, thioacetic acid, alkanethiols, and sodium thiosulfate to alkynones 6 and 15, followed by cyclization (Schemes 3 and 4).The thiocyanates 10a, b were converted to mixed disulfides 3, symmetric disulfides 4, thioethers 2, and thiols 1, using 'hard' or 'soft' nucleophiles or reducing agents, respectively (Scheme 6).

Process for the manufacture of furan derivatives

The invention is concerned with a process for the manufacture of substituted furans which are, in particular, flavorants; thereby 4-hydroxy-2-yn-1-ones or acetals or ketals thereof are cyclized with nucleophilic S-compounds to 3-S-furans, whereby this 3-S atom can be optionally substituted, and the acetylene derivatives, the 4-hydroxy-2-yn-1-ones, can be optionally 1- and/or 4-alkyl or alkenyl substituted.
