Ph <sub>2</sub> SCCO: A New Versatile CCO‐Fragment Transfer Reagent Open
ketenylidene (C 2 O) is an electronically intriguing small molecule with significant potential as a C 2 synthon in organic synthesis. However, its high reactivity has thus far precluded practical applications. Herein, we report the synthes…

Spiro-C(sp <sup>3</sup> )-atom transfer: Creating rigid three-dimensional structures with Ph <sub>2</sub> SCN <sub>2</sub> Open
The introduction of a single C-atom into organic substrates typically results in the formation of flat molecules containing unsaturated C(sp)-centers. Adding a single C(sp 3 )-atom surrounded by four σ-C–C bonds, which opens up the three-d…

Cleavage of Carbodicarbenes with N<sub>2</sub>O for Accessing Stable Diazoalkenes: Two‐Fold Ligand Exchange at a C(0)‐Atom Open
The cleavage of carbophosphinocarbenes and carbodicarbenes with nitrous oxide (N 2 O) leads to the formation of room‐temperature stable diazoalkenes. The utility of Ph 3 P/N 2 and NHC/N 2 ligand exchange reactions were demonstrated by acce…

Photochemical Approach to the Cyclohepta[<i>b</i>]indole Scaffold by Annulative Two‐Carbon Ring‐Expansion Open
We report on the implementation of the concept of a photochemically elicited two‐carbon homologation of a π‐donor–π‐acceptor substituted chromophore by triple‐bond insertion. Implementing a phenyl connector between the slide‐in module and …
