From @heechankim.bsky.social @rjgilliard.bsky.social a range of boron helices @jacs.acspublications.org.

This double-stranded diborahelicate could be transformed into luminescent borahelicates and cationic boron coordination complexes.

The Hudnall lab is hiring a Postdoctoral Fellow! Applicants excited about joining our recently relocated research group and interested in the synthesis of exotic main-group molecules, materials and heterodiatomics can email Dr. Hudnall directly. Please share!

Magnesium-Catalyzed Primary, Secondary, and Tertiary Amide Hydroboration Catalytic hydroboration of amides is highly important because the resultant amines are commonly found in natural products, pharmaceuticals, agrochemicals, dyes, and other applications. In comparison to the conventional reduction of amides using (over)stoichiometric reductants, hydroboration of amides using magnesium compounds represents a green and sustainable approach because magnesium is both Earth abundant and environmentally benign. However, there is only one report on magnesium-catalyzed deoxygenative hydroboration of secondary and tertiary amides. Here, we describe the synthesis and structural authentication of two new magnesium compounds (1 and 2) featuring a flexible PNP ligand and the utilization of 2 as a catalyst for the pinacolborane-mediated reduction of primary, secondary, and tertiary amides to amines. The reaction scope is explored, and a mechanism is proposed based on experimental and theoretical insights.

This time it's magnesium! Our latest at Inorganic Chemistry reports a Mg-catalyst that reduces all amides. Kudos to Biplab for the lead with solid support from Soumya, Devaraj, Kumar, Rajesh! Grateful to CSIR_IND for funds!

Opinion: The backlash against Australia’s ban on social media for children is misguided While balancing regulation against free speech will be tricky, something needs to be done about the serious problems that social media wreaks on our youth

I fully support this. Children under 16 shouldn't be on social media sites like the ones noted.
