A TBHP-mediated palladium-catalyzed tandem isomerization-Wacker oxidation of terminal alkenes was developed. This methodology provides a new efficient and simple route for conversion of a range of allyl arenes directly into aryl ethylketones in good yields with high chemoselectivity.
Nickel-catalyzed heck-type reactions of benzyl chlorides and simple olefins
Matsubara, Ryosuke,Gutierrez, Alicia C.,Jamison, Timothy F.
supporting information; experimental part, p. 19020 - 19023 (2011/12/21)
Nickel-catalyzed intermolecular benzylation and heterobenzylation of unactivated alkenes to provide functionalized allylbenzene derivatives are described. A wide range of both the benzyl chloride and alkene coupling partners are tolerated. In contrast to analogous palladium-catalyzed variants of this process, all reactions described herein employ electronically unbiased aliphatic olefins (including ethylene), proceed at room temperature, and provide 1,1-disubstituted olefins over the more commonly observed 1,2-disubstituted olefins with very high selectivity.
Synthesis of new cores and their use in the preparation of polyester dendrimers
Twibanire, Jean-D'Amour K.,Al-Mughaid, Hussein,Grindley, T. Bruce
experimental part, p. 9602 - 9609 (2011/01/03)
Six dendrimer and dendron cores terminated by hydroxyl groups that are neither phenolic nor cleavable by hydrogenolysis have been prepared in a consistent one-pot manner from terminal allyl groups by reduction of the product of reductive ozonolysis. Some of the terminal allyl derivatives are new and others have been prepared by new methods. The well-known O-benzylidene derivative of 2,2′-bis(hydroxymethyl)propanoic acid was shown to be the cis-stereoisomer. A new AB3-type anhydride, tris(benzyloxymethyl) acetic anhydride has been prepared. It was demonstrated that these cores and dendrons could be assembled into first and second generation homo- and mixed polyester dendrimers.
Short access to 4-alkenylbenzonitriles: Reaction of anionic reduced forms of terephthalonitrile with alkenyl bromides

Direct one-pot syntheses of 4-(ω-alkenyl)-benzonitriles in high yields have been achieved via the reaction of terephthalonitrile dianion with allyl or co-alkenyl bromides in liquid ammonia. Georg Thieme Verlag Stuttgart.
Preparation of para-terphenylylalkanethiols with different chain lengths
Mueller, Jan,Brunnbauer, Markus,Schmidt, Michael,Zimmermann, Anja,Terfort, Andreas
, p. 998 - 1004 (2007/10/03)
Terphenylylalkanethiols with different chain length were synthesized using palladium-catalyzed cross-coupling reactions. While the thiols with two and three methylene groups were obtained via photoaddition of thiopivalic acid to the respective alkenes, the longer terphenylylalkanethiols were synthesized by two consecutive Kumada cross-coupling reactions followed by a Mitsunobu reaction for the introduction of the sulfur functionality.
