Overall Water Splitting

Developing an efficient single component photocatalyst for overall water splitting under visible-light irradiation is extremely challenging. Herein, we report a metal-free graphitic carbon nitride (g-CxN4)-based nanosheet photocatalyst (x = 3.2,...

Lewis Pairs

A comparison of two catalytic, metal-free iodoperfluoro­alkylation protocols is presented. Frustrated Lewis pairs [ t Bu3P/B(C6F5)3] or phosphines/phosphites under visible light irradiation efficiently mediate the functionalization of non-activated alkenes and alkynes. A comprehensive account of the corresponding substrate scopes as well as insights into the mechanistic details of both reaction pathways are provided.

High Yields

To address the problem of using UV light to initiate traditional photoreactions, hydrazide based chromophores are evaluated as a “photo-auxiliary“ with visible light using a metal free photocatalyst to afford photoproducts in high yields.
