Addition Reactions of Phosphorus‐Centered Radicals onto Olefins: Interplay Between Stability and Reactivity

Chemistry – A European Journal, EarlyView.
The energetics of the addition reaction of P‐centered radicals onto alkenes are primarily ruled by the stability of the attacking radical, as outlined by the computational screening of a wide range of reactions. In addition, donor‐acceptor substituents at the olefin have an important tuning role.

Iron‐Mediated Electrochemical Cyclopropanation of Borodiiodomethane with Alkenes†

Chinese Journal of Chemistry, EarlyView.
This work describes an electrochemical iron‐mediated cyclopropanation of borodiiodomethane with alkenes, resulting in the formation of boro‐substituted cyclopropanes. A key feature of this study is the unexpected discovery that the cathodically generated iron ion coordinates with a biquinoline ligand in situ, facilitating the electrochemical ...

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra

Ecography, EarlyView.
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.
