The photopromoted, Ni-catalyzed acceptorless
dehydrogenation
esterification
of phenols and aromatic aldehydes has been achieved in an oxidant-
and external photosensitizer-free manner. This reliable and atom-economical
transformation was tolerant to a wide range of functional groups and
proceeded efficiently to give various aryl benzoates in moderate to
high yields. Additionally, this photocatalytic system displayed high
activity for the hydrogen-evolution cross coupling of aliphatic aldehydes
and phenols employing dual nickel and aromatic aldehyde catalysis.
Earth-abundant copper(I) coordination complexes of an imine-phosphine and a diimine have been developed as visible-light photocatalysts. Reaction of [Cu(MeCN)4]BF4 with hetero-bidentate phosphinopyrazole (phpz) ligand R1R2C3HN2PPh3 (R1 = R2 = H...
Transformation of thioesters via transition-metal-mediated C(acyl)−S bond cleavage is an emerging method to forge C-C and C-heteroatom bonds. Herein, we report the first activation of stronger C(non-acyl)–S bond of thioesters...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
