Red-light-mediated Barton decarboxylation reaction and one-pot wavelength-selective transformations

Abstract

Red-light-mediated Barton decarboxylation using catalytic zinc tetraphenylporphyrin was developed. One-pot wavelength-selective reaction within the visible light range was achieved in combination with blue-light-mediated photoredox reaction.

Red-Light-Driven Bifunctionalization of Styrene Derivatives

“…7 Their high rigidity and large molar absorption coefficient are anticipated to enable long-duration operation with a minimal catalyst loading. Thus, longer-wavelength-light-mediated re- actions facilitated by phthalocyanine catalysts can be expected to unveil novel synthetic pathways, particularly the direct modification of visible-light-absorbing materials, tandem reactions with shorter-wavelength-light-mediated reactions, 8 and under shielded conditions such as those in cell reactions. 9 Here, we present a method for the bifunctionalization of styrene derivatives catalyzed by a red-light-activatable photocatalyst (Figure 1b).…”
