Organic photocatalysts are emerging as viable and more sustainable tools than metal
complexes. Recently, the field of organo‐photocatalysis has experienced an explosion in …

When aiming to synthesize molecules with elevated molecular complexity starting from
relatively simple starting materials, photochemical transformations represent an open …

Sulfur-bridged cationic diazulenomethenes were synthesized and exhibited high stability
even under basic conditions due to the delocalization of positive charge over the whole π …

The entrance channel of bimolecular reactions sometimes involves the formation of outer
complexes as weakly bound, fleeting intermediates. Here, we characterize such an outer …

Abstract The photochemical [2+ 2] cycloaddition of styrenes provides a frequently used route
for the synthesis of multi-substituted cyclobutanes. Despite the extensive studies in noble …

A novel method for the concise synthesis of cyclohepta [b] indoles in high yields was
developed. The method involves a visible‐light‐induced, photocatalyzed [2+ 2] …

Hydrochromic materials, which change color in response to moisture, are highly sought‐
after due to some unique applications such as moisture detection, humidity monitoring, anti …

Abstract A visible‐light organophotocatalytic [2+ 2] cycloaddition of electron‐deficient
styrenes is described. Photocatalytic [2+ 2] cycloadditions are typically performed with …

We developed a sulfur-embedding annulative π-extension (thia-APEX) reaction that could
construct a sulfur-embedding cationic hexagonal aromatic ring, thiopyrylium, onto …

The photochemical direct esterification of aldehydes with alcohols via in situ-generated acyl-
bromides presented in this report is an attractive complementary addition to hitherto reported …
