ChemCatChem, EarlyView.Palladium‐catalyzed telomerization of isoprene with diethylamine using non‐protic solvents and phosphite ligands with large cone angle afforded telomer 3 (T–T) in up to 90% yield and 90% selectivity. Phosphite ligands with small cone angle provided telomer 4 (H‐T) with selectivity of 43% (80% yield) and 48% (23% yield) with iPr2NH.

A new parametrization for ambient particle formation over coniferous forests and its potential implications for the future [PDF]
, 2009 Atmospheric new particle formation is a general phenomenon observed over coniferous forests. So far nucleation is either parameterised as a function of gaseous sulphuric acid concentration only, which is unable to explain the observed seasonality of ...

Rewriting Alkene Frameworks: A Practical Strategy for Nitrogen Incorporation
ChemistryEurope, EarlyView.Morandi and team developed a metal‐free method to insert nitrogen into unactivated alkenes, forming amidines and nitriles via a transient aza‐allenium intermediate. Using mild, open‐flask conditions, the process delivers high yields and broad functional group tolerance.

Effects of virus infection on release of volatile organic compounds from insect-damaged bean, Phaseolus vulgaris [PDF]
, 2003 Insects can serve as important vectors of plant pathogens, especially viruses. Insect feeding on plants causes the systemic release of a wide range of plant volatile compounds that can serve as an indirect plant defense by attracting natural enemies of ...

Anthraquinone Sulfonates as Water‐Soluble Photocatalysts: Synthetic Applications and Perspectives
ChemPhotoChem, EarlyView.The development of photochemistry in water is rapidly advancing, and the demand for water‐soluble photocatalysts is increasing. Accordingly, anthraquinone sulfonates are interesting options for the activation of organic molecules through H‐atom transfer, proton‐coupled electron transfer, or the generation of reactive oxygen species.
