Intermediates 5a, and 5b were then dehydrated to form a intermediate 12 which reacted with another acetone molecule to produce the intermediate 14. Finally, the intermediate 14 cyclized via a 1,6-cyclization re
161 Interestingly, this molecule, and even more potent aptenin analogs A4 and A5 (Figure 21), more effectively inhibit bovine than ascarid C-II. Given the structures, it is not surprising that inhibition appears to be by binding to a site that partially overlaps with the physiological ...
Allylacetone (CAS 109-49-9) is a colorless to pale yellow liquid with a strong odor. It has a basic structure consisting of an allyl group attached to an acetone molecule. This chemical is soluble in water, ethanol, and ether. It has a boiling point of 126-128°C and a density of ...
DPL currently produces 330,000 tonnes/year of phenol, 200,000 tonnes/year of acetone and 80,000 tonnes/year of IPA at its production complex at Dahej. In March, Deepak Advanced Materials Limited (DAML), another wholly owned subsidiary of DNL, began operations at its PC compounds facility at...
The present study was undertaken in order to answer the question if Cu + ions in zeolites were also able to activate another than C C double bond. We studied therefore the interaction of acetone with Cu + in zeolites CuZSM-5, CuMCM-41, CuX and CuY. IR studies showed a weakening of ...

The reaction of the dimeric complex 3 with MeI allows the insertion of a methyl group into the carbonyl group to form the PtII complex [(dcpp)Pt(C(O)Me)I] (5). Reaction of another equivalent of MeI with complex 5 leads to the formation and elimination of acetone and the bis(iodide)...
In contrast, power-to-X technologies aim to increase the volumetric storage density of hydrogen at ambient conditions by chemically binding hydrogen to a carrier molecule, such as nitrogen, CO2, aromatics or other organic compounds that can be hydrogenated. For systems, in which the hydrogenation-...
. Acetoacetate was described as an electron donor molecule in the peroxidase system and the reaction was thought to have a feasible role in decarboxylation of acetoacetate, but the in vivo significance of that was questioned[36]. In neutrophils isolated from fresh blood samples withdrawn from ...
The method can also include the step of after contacting the sample with the extraction solution, analyzing the sample using tandem mass spectrometry. The contacting can derivatize at least one succinylacetone molecule to 3-(5-methyl-1H-pyrazol-3-yl) proprionic acid (MPP). The C1-3 linear ...
