Conjugated dienes can be initially converted to their zirconocene complexes most conveniently by their reaction with (C5H5)2ZrCl2 and freshly ground Mg; the resultant complexes can then be protonolysed with 3 mol dm-3 HCl to give regioselectively monoenes corresponding to partial hydrogenation of the more highly substituted double bond.

An easily accessible copper(I)/N-heterocyclic carbene (NHC) complex enables a regioselective hydride transfer to allylic bromides, an allylic reduction. The resulting aryl- and alkyl-substituted branched α-olefins, which are valuable building blocks for synthesis, are obtained in good yields and regioselectivity. A commercially available silane, (TMSO)2Si(Me)H, is employed as hydride source. This protocol offers a unified alternative to the established metal-catalyzed allylic substitutions with carbon nucleophiles, as no adaption of the catalyst to the nature of the nucleophile is required.
PROCESS FOR PRODUCING PHENYL-ALKANES USING OLEFIN ISOMERIZATION AND PARAFFIN RECYCLE
-
Page/Page column 17-19, (2008/06/13)
A process for producing phenyl-alkanes by paraffin dehydrogenation followed by olefin isomerization and then by alkylation of a phenyl compound by a lightly branched olefin is disclosed. An effluent of the alkylation section comprises paraffins that are recycled to the dehydrogenation step. A process that sulfonates phenyl-alkanes having lightly branched aliphatic alkyl groups to produce modified alkylbenzene sulfonates is also disclosed. In addition, the compositions produced by these processes, which can comprise detergents, lubricants, and lubricant additives, are disclosed.
Ni-catalyzed alkylative dimerization of vinyl Grignard reagents using alkyl fluorides
Terao, Jun,Watabe, Hiroyasu,Kambe, Nobuaki
, p. 3656 - 3657 (2007/10/03)
Alkyl halides underwent unique cross-coupling reaction with vinylmagnesium chloride in the presence of Ni catalyst to give 2-alkyl-3-butenyl Grignard reagent (1) in high yields. This reaction proceeded efficiently at 25 °C in THF using primary and seconda
