cross Ketonic Decarboxylation, i.e., the formation of a ketone from two different carboxylic acids, and the reketonization, i.e., the transformation of a carboxylic acid into a ketone employing a ketone as alkyl transfer agent, may be interesting alternatives to classical pathways involving meta...
48 Both methods utilize trimethylsilyl chloride (TMS-Cl) at some point during ketone preparation; the former method of Rubottom introduces TMS-Cl once addition of the alkyllithium to the carboxylic acid is complete. This was done in an effort to trap residual methyllithium and allow the use ...
Methyl isopropenyl ketone is produced from methyl ethyl ketone and paraformaldehyde under mild reaction conditions utilizing a catalyst comprising a halogen acid salt of a secondary amine and (a) a non-soluble solid oxide of an element selected from Groups IB, IIIA, IVA, IVB, VA, VB, VIB and...

ChEBI: Methyl nicotinate is a member of pyridines and an aromatic carboxylic acid. Application Methyl nicotinate can be employed as a precursor in the synthesis: Di-3-pyridyl ketone ligand, which is used in the preparation of silver(I) complexes for the derivation of coordination polymeric chains...
ChEBI: Methyl methacrylate is an enoate ester having methacrylic acid as the carboxylic acid component and methanol as the alcohol component. It has a role as an allergen and a polymerisation monomer. It is an enoate ester and a methyl ester. It is functionally related to a methacrylic acid....
