Correction to “Simple, Chemoselective, Catalytic Olefin Isomerization”
Page 16788 and Supporting Information page SI-4. Entry 13 was inadvertently omitted from Table 1 and S.I. Table 1. This entry suggests mechanistic overlap between our alkene isomerization and hydrogen atom transfer radical polymer-ization, more so than entry 12 alone. The complete S.I. Table 1 is shown below. This is an open access article published under an ACS AuthorChoice License, which perm...
متن کاملSimple, Chemoselective, Catalytic Olefin Isomerization
Catalytic amounts of Co(Sal(tBu,tBu))Cl and organosilane irreversibly isomerize terminal alkenes by one position. The same catalysts effect cycloisomerization of dienes and retrocycloisomerization of strained rings. Strong Lewis bases like amines and imidazoles, and labile functionalities like epoxides, are tolerated.
متن کاملPrevention of undesirable isomerization during olefin metathesis.
1,4-Benzoquinones have been found to prevent olefin isomerization of a number of allylic ethers and long-chain aliphatic alkenes during ruthenium-catalyzed olefin metathesis reactions. Electron-deficient benzoquinones are the most effective additives for the prevention of olefin migration. This mild, inexpensive, and effective method to block olefin isomerization increases the synthetic utility...
متن کاملCatalytic C-h/olefin coupling.
The cleavage and addition of ortho C-H bonds in various aromatic compounds such as ketones, esters, imines, imidates, nitrile, and aldehydes to olefins and acetlylenes can be achieved catalytically with the aid of ruthenium catalysts. The reaction is generally highly efficient and useful in synthetic methods. The coordination to the metal center by a heteroatom in directing groups such as carbo...
متن کاملA One-Pot Tandem Olefin Isomerization/Metathesis-Coupling (ISOMET) Reaction
A tandem catalytic reaction has been developed as part of a process to discover tungsten-based olefin metathesis catalysts that have a strong preference for terminal olefins over cis or trans internal isomers in olefin metathesis. This tandem isomerization/terminal olefin metathesis reaction (ISOMET) converts Cn trans internal olefins into C2n−2 cis olefins and ethylene. This reaction is made p...
