Ph2SCCO: A New Versatile CCO‐Fragment Transfer Reagent
Substituted cyclopropanes have high value as versatile synthetic intermediates, used for constructing a wide range of useful structural motifs,[1, 2] and they are frequently found in natural products.[3, 4] They constitute key structural elements in pharmaceutical molecules.[5] In fact, cyclopropanes rank as the 10th most commonly used ring system in small-molecule drugs.[6] The structural diversity of substituted cyclopropanes is remarkably broad, ranging from simple monocyclic compounds to...

Cleavage of Carbodicarbenes with N2O for Accessing Stable Diazoalkenes: Two‐Fold Ligand Exchange at a C(0)‐Atom
In 1961 Ramírez and co-workers described the synthesis of Ph3P=C=PPh3, the first carbodiphosphorane (CDP), which can be represented by a series of zwitterionic/ylidic Lewis-structures Ia–Ic (Scheme 1A).1 In 2006, Frenking reinterpreted the electronic structure of CDPs as carbon(0) compounds in which a C(0)-atom is flanked by two neutral donor ligands (Ph3P→C←PPh3; Id) similar to transition metal coordination compounds, coining the term carbones.2 Based on this bonding analysis and the...
