Nickel-Catalyzed Arylboration of Alkenylarenes: Synthesis of Boron-Substituted Quaternary Carbons and Regiodivergent Reactions
A method for the construction of boron-substituted quaternary carbons or diarylquaternary carbons by arylboration of highly substituted alkenylarenes is presented. A wide range of alkenes and arylbromides can participate in this reaction thus allowing for a diverse assortment of products to be prepared. In addition, a solvent dependent regiodivergent arylboration of 1,2-disubstituted alkenylarenes is presented, thus greatly increasing the scope of products that can be accessed.

Discrete iron complexes for the selective catalytic reduction of aromatic, aliphatic, and α,β-unsaturated aldehydes under water-gas shift conditions
Iron-catalyzed reductions: Selective iron-catalyzed reduction of aldehydes with hydrogen generated in situ by the water-gas shift reaction is presented (see scheme). The generality and selectivity of this mild procedure are demonstrated by the efficient reduction of various aromatic, aliphatic and α,β-unsaturated aldehydes.
Application of LB-Phos·HBF4 in the Suzuki coupling reaction of 2-bromoalken-3-ols with alkylboronic acids
LB-Phos·HBF4 was used in the Suzuki coupling reaction of 2-bromoalken-3-ols with alkylboronic acids to give the coupling products in moderate to good yields. Substituents such as benzyl, phenyl, allyl, and alkyl are tolerated at the 1-and 3-pos

Highly enantioselective bioreduction of 2-fluorocinnamyl alcohols mediated by Saccharomyces cerevisiae
Biocatalytic reduction of 2-fluorocinnamyl alcohols mediated by Saccharomyces cerevisiae was investigated in phosphate buffer solutions. Product analysis clearly showed that (S)-2-fluoro-3-arylpropanols were afforded in high yields with up to 92% ee value.

Allyl alcohols and organocerium reagents, II. - Mechanism and extensibility of the reaction
Alkylcerium reagents add to the multiple bonds of allyl and propargyl alcohols in good yields and under mild conditions. The double bond can be reduced with lithium aluminum hydride in the presence of cerium trichloride. The regiochemistry of the attack depends on electronic factors.
