Reactions of Saturated and Unsaturated Tertiary Alkyl Halides and Saturated Secondary Alkyl Iodides with Lithium Aluminum Deuteride. Convincing Evidence for a Single-Electron-Transfer Pathway
Autor: Catherine O. Welder, Eugene C. Ashby
Publikováno v: The Journal of Organic Chemistry. 63:7707-7714
Reactions of saturated secondary and tertiary alkyl halides with LiAlH4 (LAH) and LiAlD4 (LAD) have been carried out, and convincing evidence for a single-electron-transfer (SET) pathway has been obtained. Reactions involving saturated alkyl halides

Evidence for Single-Electron Transfer in the Reactions of Unhindered Saturated Primary Alkyl Iodides with Lithium Aluminum Hydride. Reactions of 1-Halooctanes with Lithium Aluminum Deuteride
Autor: Catherine O. Welder, Eugene C. Ashby
Publikováno v: The Journal of Organic Chemistry. 62:4829-4833
Evidence for single-electron transfer (SET) in the reactions of lithium aluminum hydride (LAH) with unhindered, saturated primary alkyl halides has not been available. In this study, experiments have been carried out that provide convincing evidence

Convincing Evidence, Not Involving Cyclizable Radical Probes, That the Reaction of LiAlH4 with Hindered Alkyl Iodides Proceeds Predominantly by a Single Electron Transfer Pathway
Autor: Eugene C. Ashby, Catherine O. Welder
Publikováno v: The Journal of Organic Chemistry. 62:3542-3551
Previous workers have maintained that evidence for the radical nature of the reaction of LiAlH4 with sterically hindered alkyl iodides is due to radical initiation by impurities followed by a halogen atom radical chain process involving the cyclizabl

Mechanistic Study of the Reactions of 1,1-Dihalo-2-methyl-2-phenylpropanes with LDA. Evidence for Radical and Carbene Pathways
Autor: and Ali Mehdizadeh, Abhay K. Deshpande, Eugene C. Ashby
Publikováno v: The Journal of Organic Chemistry. 61:1322-1330
An attempt was made to determine the mechanisms involved in the reactions of the model systems 1,1-dichloro-2-methyl-2-phenylpropane (1) and 1,1-diiodo-2-methyl-2-phenylpropane (2) with LDA. These systems were chosen as ones capable of providing evid

The effect of reactor surfaces on single electron transfer reactions. The reaction of 1-Iodo-2,2-dimethylhexane with lithium aluminum deuteride
Autor: Eugene C. Ashby, Catherine O. Welder
Publikováno v: Tetrahedron Letters. 36:7171-7174
Reactions of 1-iodo-2,2-dimethylhexane (4) with LiAlD4 have been carried out in a variety of reaction vessels. In vessels of used pyrex, teflon, and stainless steel, the surface of the reactor plays a role in the product distribution. However, treate

Mechanism of Reaction of Geminal Dihalides with Lithium Aluminum Hydride. Evidence for Single Electron Transfer as the Major Reaction Pathway
Autor: Eugene C. Ashby, Abhay K. Deshpande
Publikováno v: The Journal of Organic Chemistry. 59:3798-3805
The reactions of a sterically hindered geminal dichloride (4a) and the corresponding diiodide (4b) with LiAlH 4 (LAH) were found to involve an electron-transfer mechanism. Whereas the monochloro analog (8) of (4a) is inert toward LAH, (4a) was more r
