Abstract:The dicarbonylation of 1,3‐butadiene to adipic acid derivatives offers the potential for a more cost‐efficient and environmentally benign industrial process. However, the complex reaction network of regioisomeric carbonylation and isomerization pathways, make a selective and direct transformation particularly difficult. Here, we report surprising solvent effects on this palladium‐catalysed process in the presence of 1,2‐bis‐di‐tert‐butylphosphin‐oxylene (dtbpx) ligands, which allow adipate diester formation fr… Show more
“…In addition, the catalytic system was also effective for the conversion of numerous other nucleophiles. 177,[182][183][184][185] With respect to the industrial realization of such a process, it is important to note that apart from the technical success, the implementation of such a methodology will strongly depend on the development of the different feedstock prices (e.g. benzene versus 1,3-butadiene).…”

“…7 The Fischer–Tropsch process serves as an exceptional example to yield carbon chain (C4–C10) products through controlled homologation and hydrogenation of CO. 8 Moreover, double carbonylation at adjacent or distant positions can be accomplished under certain conditions. 9 Adjacent double carbonylation has received great interest as they form oxamates, α-keto amides, and oxamides, which are useful natural products and pharmaceuticals. 10…”
The monocarbonylation and dicarbonylation reactions are well-established reactions in the carbonylation chemistry. This work reports unusual oxidative adjacent triple carbonylation of tertiary amine towards oxomalonamide synthesis using Pd catalyst. The...
A new cobalt catalyst is presented for the domino hydroformylation-reductive amination reaction of olefins. The optimal Co-tert-BuPy-Xantphos catalyst shows good to excellent linear-to-branched (n/iso) regioselectivity for the reactions of aliphatic alkenes with aromatic amines under mild conditions. This system is far more selective than traditional cobalt(I) catalysts and even better than most known rhodium catalysts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
