Electroreductive Carboxylation of Benzylphosphonium salts with CO2 Through the Cleavage of the C(sp3)-P Bond Herein, electrochemical carboxylation of benzylphosphonium salts was achieved by cleavage of the C(sp3)-P bond, and various valuable arylacetic acids could be synthesized by this strategy. Also, based on control experiments and previous works, a plausible reaction mechanism was proposed to explain the reaction process.

Electrochemical Benzylic Deuteration of p-QMs Enabling the Synthesis of Benzylic Deuterated Diarylmethanes Herein, electroreductive umpolung benzylic deuteration of p-QMs using cheap and easily accessible D2O as a deuterium source was realized. Various value-added benzylic deuterated diarylmethanes can be synthesized without the requirement of noble metal catalysts, redox reagents, and strong bases.

1. Introduction Time spent on screen media such as social media, gaming, and TV has substantially increased for children and adolescents over the last two decades [1,2]. Nagata et al. [3] reported that the average daily screen time was 7.7 h per day in a national sample of adolescents (N = 5412) during the COVID-19 pandemic, which is about twice as much as the pre-pandemic estimates (3.8 h per day).
