Photoinduced DiazoCarbene-Promoted C(sp<sup>3</sup>)–H Oxidative Cross-CouplingReaction for α‑Triazolationof Isochromans

A photocatalytic diazo triplet carbene-promoted C(sp<sup>3</sup>)–H oxidative coupling of isochromans and triazoles was developed in up to 83% yield at room temperature in air. The radical-like triplet carbenes were used as efficient HAT acceptors, and the possible synergistic HAT enabled the unprecedented process with a high regioselectivity.

Abstract

A photocatalytic diazo triplet carbene-promoted C(sp<sup>3</sup>)–H oxidative coupling of isochromans and triazoles was developed in up to 83% yield at room temperature in air. The radical-like triplet carbenes were used as efficient HAT acceptors, and the possible synergistic HAT enabled the unprecedented process with a high regioselectivity.
