supporting information; experimental part, p. 4496 - 4499 (2009/12/06)
A selective Iron-catalyzed cross-coupling of alkyl halldes with alkenylzinc reagents Is described. Primary and secondary alkyl chlorides, bromides, and iodides take part In the reaction to give the corresponding olefins In good to excellent yields In a stereospecific manner. High functional group compatibility Is also demonstrated by using combinations of substrates possessing rather reactive substituents.
The thionophosphate-thiolophosphate photoisomerization proceeds predominantly through a non-chain radical pathway. Synthetically viable benzylation of tetrahydrofuran, propan-2-ol and olefins

The photoirradiation of thionophosphates, ROP(S)(OEt)2, derived from benzyl and vinylogously benzyl alcohols in CH3CN, with a Hanovia medium-pressure mercury lamp in a quartz vessel leads to the formation of the corresponding thiolophosphates, RSP(O)(OEt)2, through a non-chain radical pathway. This behavior of thionophosphates is unlike that of the related phosphates, which react through ionic dissociation-recombination processes. When the irradiation is conducted in solvents such as PriOH, THF and toluene, benzylation of these solvents takes place in synthetically respectable yields. Irradiation of thionophosphates in CH3CN leads to a convenient allylic benzylation of olefins.
Palladium-Catalized Oxidative Cyclization of 1,5-Dienes. Influence of Diferent Substitution Patterns on the Regio- and Stereochemistry of the Reaction

Oxidative cyclization of 1,5-dienes in acetic acid in the presence of the Pd(II) regenerating catalyst system Pd(OAc)2/MnO2/p-benzoquinone has been shown to yield, depending on the structure of the 1,5-diene, acetoxyexomethylenecyclopentanes or acetoxyvin
OLIGOMETHYLENATION OF PHENYLALLENE WITH DIAZOMETHANE IN THE PRESENCE OF PALLADIUM DIACETATE
Lukin, K. A.,Zefirov, N. S.
, p. 82 - 86 (2007/10/02)
In the reaction of phenylallene with diazomethane in the presence of palladium(II) acetate oligomethylenation takes place in addition to cyclopropanation.It leads to the inclusion of three and four equivalences of methylene in the allene molecule.
