Objective evaluation of the first post-lockdown on physical activity, sedentary behavior and food choice in a sample of French young adult students.

From mid-March through early May 2020, France limited outdoor activities to one hour per day because of the Covid-19 epidemic. This inside lockdown could have a lasting impact on post-lockdown sedentary and physical activities and food choice. The aim of this study is to compare behaviors before and after the lockdown in a sample of French young adult students (sex ratio = 1:1, 22 ± 3 y old).

Five-component, one-pot synthesis of an electroactive rotaxane comprising a bisferrocene macrocycle.

The templated clipping of a ferrocene-grafted isophthalic acid derivative to encircle a hydrogen-bonding axle through the reaction with 1,4-bis(aminomethyl)benzene is described. The constituent electroactive macrocycle of the resultant [2]rotaxane is a homologue of the versatile benchmark tetraamide variant developed by Leigh and co-workers. The relative templating effect of different hydrogen-bonding motifs in rotaxane and pseudorotaxane generation is compared, with yields varying from 0 to 41%.

Metal-free and light-promoted radical iodotrifluoromethylation of alkenes with Togni reagent as the source of CF and iodine.

A light-promoted methodology for the iodotrifluoromethylation of alkenes was developed. For the first time a Togni reagent was exploited as the source of both the CF group and iodine atom. Preliminary mechanistic studies suggest that both CFI and 2-iodobenzoic acid are direct sources of the iodine atom that is transferred to the products.
