Hydrogenation of alkenes via cooperative hydrogen atom transfer

Radical hydrogenation via hydrogen atom transfer (HAT) to alkenes is an increasingly important transformation for the formation of thermodynamic alkane isomers. Current single-catalyst methods require stoichiometric oxidant in addition to hydride (H-) source to function. Here we report a new approach to radical hydrogenation: cooperative hydrogen atom transfer (cHAT), where each hydrogen atom donated to the alkene arrives from a different catalyst. Further, these hydrogen atom (H?) equivalents are generated from complementary hydrogen atom precursors, with each alkane requiring one hydride (H-) and one proton (H+) equivalent and no added oxidants. Preliminary mechanistic study supports this reaction manifold and shows the intersection of metal-catalyzed HAT and thiol radical trapping HAT catalytic cycles to be essential for effective catalysis. Together, this unique catalyst system allows us to reduce a variety of unactivated alkene substrates to their respective alkanes in high yields and diastereoselectivities and introduces a new approach to radical hydrogenation.

Lanthanoid-catalyzed ring-opening reaction of epoxides with acyl halides

Eu(dpm)3 [dpm: dipivaloylmethanate] catalyzes the ring-opening reaction of epoxides with acyl halides affording the corresponding 2-haloalkyl esters. The stereochemical course was confirmed as trans-addition in the case of the reaction of cyclo

A new synthetic method for haloalkyl carboxylic esters from the radical ring cleavage of cyclic acetals with haloform

A one-pot reaction of cyclic acetals with haloform catalyzed by AIBN(2,2'-azobisisobutyronitrile) provides a novel convenient way to prepare directly haloalkyl carboxylic esters in good yields.

Reactions of 1,3-dioxolanes with Iodine Monochloride: Formation of Chlorohydrin Esters and Diol Monoesters

2-Mono-substituted 1,3-dioxolanes are oxidised by iodine monochloride to the appropriate 2-substituted 1,3-dioxolan-2-ylium ions, whose stability is dependent upon the presence and nature of substituents on C-4 and C-5.Some dioxolanylium ions are labile and under the reaction conditions afford chlorohydrin esters, with inversion of configuration taking place at the ring carbon attacked by chloride.Others are stable under the reaction conditions and may be converted on aqueous workup to diol monoesters with retention of configuration at C-4 and C-5.The effect of substituents and reaction conditions on these competing reactions are described.The stereo- and regio-chemistry of both hydroxy- and chloro-ester formation was confirmed through NMR studies, which necessitated the prior detailed analysis of the 1H and 13C spectra associated with the acyloxy sidechains of the relevant esters.

Vicinal chloroesters are formed in high yield from the reaction of oxiranes and benzoyl chloride in the presence of organotin halide - triphenylphosphine complex with enhanced regioselectivity in oxirane ring cleavage.

Reaction of 1,3-dioxolans with Iodine Monochloride: the Scope and Mechanism of Formation of 1,3-dioxolan-2-ylium Dichloroiodates(I)

Treatment of a series of 2-substituted-4,4,5,5-tetramethyl-1,3-dioxolanes with iodine monochloride afforded the appropriate 2-substituted-4,4,5,5-tetramethyl-1,3-dioxolan-2-ylium dichloroiodate(I) salts in excellent yields.In contrast to the stable 2-aryl-substituted salts, the 2-alkyl and unsubstituted derivatives were relatively labile.While 2-phenyl-1,3-dioxolan and 2-phenyl-1,3-dioxan afforded low yields of unstable salts,crystalline products could not be isolated from 4,5-disubstituted dioxolans.The reaction was inhibited by electron-withdrawing 4- and 5-substituents.From a study of the effects of photolysis and added iodine, the mechanism is proposed to involve a hydride ion transfer.Possible reasons for the formation of dichloroiodate(I) rather then monohalide salts, are outlined.The stability of the 2-aryl-substituted salts is dicussed in terms of charge distribution in the cation and possible aryl-anion interactions.
