Five new, intensely green diferrocenylphenylmethylium complexes 1+-5+ with electron donating (EDG: 4-MeO, 4-Me, 4-Br) or withdrawing (EWG: 3,5-CF3, 4-nC6F13) substituents were synthesized and fully characterized. The substituent influence on their electro

While methods for the racemic dihalogenation and halohydroxylation of alkenes have been known for decades, enantioselective variants of these processes remain elusive. Initial attempts were made to overcome this long-standing challenge by exploring the potential of chiral, crystalline, sulfur-derived halonium reagents to accomplish the asymmetric dichlorination and iodohydroxylation of 1,2-dihydronaphthalene. Asymmetric dichlorination of this substrate was achieved in 57% yield and 14% enantiomeric excess (ee), but asymmetric iodohydroxylation was much more successful, giving 67% yield and 63% ee. Thorough studies were made of these processes, including investigation of various chiral sulfide derivatives, their substrate scopes, and the reaction conditions.

Page/Page column 13-14, (2008/06/13)
The invention relates to a method for producing aryllithium compounds and to their reaction with suitable electrophiles to obtain compounds of formula (V), by reacting halogen aromatics (I) with lithium metal to obtain an aromatic lithium compound (II), which, as a lithiation agent, reacts with aromatic halogen compounds (III) in a halogen-metal exchange reaction to form the corresponding lithium aromatics (IV). Said aromatics can be reacted in an additional step with a corresponding electrophile to form the desired product (V). Said method is illustrated by equation (I), in which Ar represents phenyl, pyridyl or naphthyl, which are optionally substituted with a radical from the group consisting of methyl, primary, secondary or tertiary alkyl, cycloalkyl, phenyl, substituted phenyl, aryl, heteroaryl, alkoxy, dialkylamino, alkylthio, fluoro, bromo; Hal1 = fluorine, chlorine, bromine or iodine, Hal2 = chlorine, bromine or iodine; the groups X1-5 independently of one another represent either carbon, or the group XiRi (i = 1-5) represents nitrogen, or two respective adjacent groups XiRi, linked by a formal double bond, together represent O (furane), S (thiophene), NRH or NRi (pyrroles). The groups R1-5 represent substituents from the group containing hydrogen, methyl, primary, secondary or tertiary, cyclic or acyclic alkyl groups with 2 to 12 C atoms, in which optionally one or more hydrogen atoms are replaced by fluorine or chlorine, e.g. CF3, substituted cyclic or acyclic alkyl groups, alkoxy, dialkylamino, alkylamino, arylamino, diarylamino, phenyl, substituted phenyl, heteroaryl, substituted heteroaryl, alkylthio, arylthio, diarylphosphino, dialkylphosphino, alkylarylphosphino, dialkyl-, arylalkyl- or diarylaminocarbonyl, monoalkyl- or monoarylaminocarbonyl, CO2-, alkyl- or aryloxycarbonyl, hydroxyalkyl, alkoxyalkyl, fluorine or chlorine, nitro, cyano, aryl- or alkylsulphone, aryl- or alkylsulphonyl, or two respective groups R1-5 together can represent an aromatic, heteroaromatic or aliphatic fused ring.
