Summary

We introduce a C–H coupling process in which an aromatic C–I position serves as trampoline for targeting various aromatic C–H positions. The reaction is set in motion by an interaction between the λ³-iodane ArI(OAc)₂ and the π system of polyunsaturated organosilanes. In particular, the silyl-terminated enynes engage in fully regioselective ortho and para C–H functionalization, with selectivity switch achieved by reversing the order of the substrate's ene and yne fragments. Density functional theory (DFT) calculations show that the ortho selectivity is governed by a [3,3] sigmatropic rearrangement, while the para coupling occurs through a directional three-point π interaction of the enyne-derived cationic π system, giving rise to an essentially barrierless [5,5] sigmatropic rearrangement. Furthermore, iodane-guided C–H functionalization of 2-iodonaphthalene could be directed to the ultra-remote C6 position through further π extension of the organosilanes partner. The latter reaction represents a nearly unprecedented example of a formal [7,7] sigmatropic rearrangement.21:T49a,With a booming population, global food demand is increasing rapidly. Various methods have been proposed to alleviate heat stress and improve yields for agriculture in hot climates. However, the damage caused by high root temperatures cannot be avoided due to a lack of efficient regulation strategies. In this work, we investigate a new soil cooling strategy based on the daytime radiative cooling film. This film has a high emissivity across the atmospheric window along with a high reflectivity in the solar spectrum. With a soil temperature drop of 12.5°C, the germination rate
