Metallatetrahedrane Intermediates in Alkyne Metathesis
Alkyne metathesis typically operates through a metallacyclobutadiene intermediate. On the other hand, metalltetrahedranes are commonly considered as off-cycle byproducts that interfere with the reaction. The Lee group recently isolated a Mo(VI)-metallatetrahedrane that was catalytically active. Here, they investigate the factors that determine the formation of metallatetradedranes and how they affect the alkyne metathesis mechanism.

Sodium Chloride induced shape deformations of polymersomes
NaCl induced shape deformations of polymersomes composed of amphiphilic triblock copolymers were analyzed using Small Angle Neutron and X-ray Scattering. Spherical polymersomes transform from spherical to multi-vesicular structures with increasing salt concentrations. While the membrane thickness shows an initial decrease and then a gradual increase, the inter-layer water thickness decreased until a constant value is reached. [DOE Open Access on 3/2022]
Self-assembly of peptoid polymers
The intermolecular interactions amongst the peptoid polymers can be fine-tuned by controlling the N-substituent sidechain structures. In this study, branching pattern of peptoid polymer sidechains have been shown to effectively modulate the molecular shape of entire polymer chains and the collective assembly of polymers in solution to form two- or three-dimensional hierarchical structures.
