Since carbon–carbon (C–C) covalent bonds are rigid and robust, the bond length is, in general, nearly constant and depends only on the bond order and hybrid orbitals. We report here direct visualization of the reversible expansion and contraction of a Csp3–Csp3 single bond by light and...
2. Different Hybrid Catalysts in C─C Bond Formation Reactions 2.1. Hybrid Catalysis Applied to Carbene Insertion Reactions Carbene insertion into C─H bonds provides an attractive and versatile synthetic approach for the formation of new C─C bonds, an essential reaction for increasing the complexity...
