Diarylbenzo-and naphthopyrans are one of the important and well-known classses of
organic photochromic systems. Their photolysis leads to highly colored o-quinonoid …

The good understanding of a photochromic reaction mechanism requires the establishment
of the list of all the transient species and the definition of their connecting processes. The …

An operationally simple photochemical strategy for the direct arylation of oxindoles with
(hetero) aryl halides in the absence of both transition metals and photoredox catalysts has …

Exfoliation of layered porous metal-organic frameworks (MOFs) in a top-down fashion
constitutes a successful approach to 2D metal-organic nanosheets (MONs), the analogs of …

The biaryl coupling between a nucleophile (Ar δ−: arylboronates or arylsilanes) and an
electrophile (Ar δ+: arylhalides) represents the state of the art in carbon–carbon bond …

A visible‐light driven Suzuki cross‐coupling reaction was performed with colored and bench‐
stable arylazosulfones in the presence of Ph3PAuCl (5 mol%) as the catalyst. The absence …

Photolysis of regioisomeric helical chromenes 1 and 2 leads to colored reactive
intermediates. While the latter generally decay quite rapidly, they are found to be longer …

A series of new photochromic fused-naphthopyrans with an alkyl bridge between the pyran
ring and the naphthalenic core was synthesized in several steps from 4-(bromomethyl) …

The fluoride-mediated desilylation reaction has been exploited, for the first time, to trigger
ring-opening of photochromic diarylbenzo-/naphthopyrans into highly colored anionic …

In this work, for the first time benzophenone and dipyridyl ketone were introduced as the
core structure to synthesize two new D–A–D type molecules, namely BP-DC and PT-DC …
