What is the mechanism for cleaving the C–C bond?
- In this regard, the mechanism proposed for cleaving the C–C bond comprises a series of C–H bond cleavage reactions to access a benzyne-type intermediate [ h2 - C2-C6H4(NCCN)]W (PMe3)4H2, from which [k2 - C2-C6H4(NC)2]W (PMe3)4 is obtained via a sequence that involves reductive elimination of H2 and C–C bond cleavage.
What is the key to the carbon–nitrogen triple-bond cleavage?
- The DFT calculations also revealed the detailed reaction mechanism and indicated that the key for the carbon–nitrogen triple-bond cleavage could be attributed to the presence of nucleophilic nitrogen atom in one of the intermediates. A triple bond having three shared electron pairs between two atoms is known as one of the strongest chemical bonds.
Is cleavage of a triple bond possible without transition metals?
- Recently, chemistry of single-bond cleavage by using main-group element compounds is rapidly being developed in the absence of transition metals. However, the cleavage of a triple bond using non-transition-metal compounds is less explored.
What is the effect of metal to ligand bonding?
- The metal to ligand bonding creates a synergic effect which strengthens the bond between CO and the metal . SOLVED QUESTIONS 1 MARK QUESTIONS 1. What are ambidentate ligands?
